Third-party cookie will be blocked - Future Chrome Issue

[kingyyyyyy]

Describe the bug Chrome is showing an issue in console, that in the near future third-party cookie will be blocked.

To Reproduce Steps to reproduce the behavior:

1. Go to: Any website that has the Mailchimp for Woocommerce Plugin Installed, and shows their reviews on the site.
2. Click on: Open Developer Console in Chrome (Not Incognito).
3. Scroll down to: Look at the console issues that are titled: Third-party cookie will be blocked.
4. See error: On the Issues tab see the following: https://i.gyazo.com/88d7d20e645ada9c11c1f267ee4cb1c1.png

Expected behavior A clear and concise description of what you expected to happen. Is there a plan/update regarding this issue in order to resolve it before the change goes ahead with the Chrome browser? Don't want the plugin front-end to end up causing issues or not showing reviews.

Operating environment (please complete the following information):

• Store URL: Can be provided privately.
• Plugin version: 3.6
• WooCommerce version: 8.5.2
• Wordpress version: 6.4.3
• PHP version: 7.4.33

Things to verify before submitting a ticket

• Verify you are using the most up to date plugin version.
• Enable "Remote Diagnostics" from the plugin's Settings tab (if possible)
• If there any fatal errors in WooCommerce, please provide (WooCommerce -> Status -> Logs)
• If you're using the current version of the plugin, it utilizes a queue powered by Action Scheduler. It depends on WP_CRON to be activated with your hosting provider. Please confirm with your host that it's enabled.
• Do you have any caching plugins or services running? If you're using Redis, Nginx, or MemCache, see if you or your hosting provider can exclude certain paths to the REST API and /wp-json/mailchimp-for-woocommerce. Visit our Wiki help page on this topic for more information.
• If you have a large number of plugins being used, you may need to bump up your memory limit on your server (1GB for example) to accommodate the initial sync.

Hi @kingyyyyyy, good to hear from you again. We tested this out in our staging environment and were unable to replicate. Do you have a URL you can share? We'll see if we can spot something.

Hello,

Here you go: https://myeliquidsupplies.com/

You'll see it on the homepage, using Google Chrome, and any other page that has a Trustpilot widget.

Same issue with Cloudflare Rocket Loader On or Off.

Here is the docs: https://developers.google.com/privacy-sandbox/3pcd#report-issues

I might be the 1% of Chrome users that can see it atm?

EDIT: https://developers.google.com/privacy-sandbox/blog/cookie-countdown-2024jan

It seems I can't see the eye icon, so I'm not a part of the 1%.

I also have a Staging site running with the majority of the plugins disabled (all cache, CDN and performance plugins disabled too) and I still see the issue there, with Chrome.

Hello, I'm seeing lots of clients with this problem. How did you solve it? Thank you

Not solved. It's a major issue for all users, due to cookie policy changes, so I assume the developers are working on a fix.

[jbeltran73-2]

ok, thank you for your fast response

Yep.. I have also encountered this issue, with this message flooding the console with nearly five hundred warnings: 'Third-party cookie will be blocked. Learn more in the Issues tab.' It appears mostly where I embed YouTube videos, and it's unclear whether it's related to cookies or youtube-nocookie.com. This issue needs to be addressed as soon as possible because it's impossible to navigate the site when the console is filled with over 500 messages of 'Third-party cookie will be blocked. Learn more in the Issues tab.' It's just impossible to use the site. What's even more concerning is that if the site is of a business nature, it's a loss of revenue because people leave the site without even viewing the content. Even if you navigate to the youtube.com page, you'll see these warnings. I think they rushed to implement this without testing, although as far as I know, 'Third-party cookie will be blocked. Learn more in the Issues tab.' has been in testing for a while now. These warnings cause more problems than the third-party cookies themselves.

Yep, it's to do with all 3rd party cookies per see, so the developers need to migrate/adapt with the solutions Google has provided, in advance: https://developers.google.com/privacy-sandbox/3pcd#report-issues

Tech news sites are also talking about this phase out.

If you check in Firefox or Safari, you will see the cookies are already blocked, as they have already implemented this.

Indeed, that's understandable. But the new standard currently blocks everything indiscriminately. They are even blocking themselves. I think it's a clear bug.

I'm currently having this happening in my project when implementing Google recaptcha, it's ironic that they block their own services.
