Describe the bug

I've just use Paywall feature and got many crash report message like this There is no singleton instance. Make sure you configure Purchases before trying to get the default instance. More info here: https://errors.rev.cat/configuring-sdk

I think the issue happen when the user open paywall and leave the app. And when they comeback, the activity resume and have this issue.

To reproduce the issue you can enable "Don't keep activities" on Developer options. And then ope paywall in the app, leave paywall open and change to other app. When comeback you can see the issue or you can't close the paywall.

Hey @sonbui00 ,

Can you please confirm that you have configured the SDK before showing the Paywall in this instance? You might be able to confirm that from debug logs or stack trace of the crash report that you get. Once you get that information, can you please share it here so we can look further into it?

[sonbui00]

@michaelAtRC Confirmed. I can open Paywal and make purchase normally. The issue happen when I leave the Paywall open and change to other app in long time and come back, not when I open paywall first time.

Hi @sonbui00, Is this still happening with the latest version?

[sonbui00]

@nyeu my version: purchases_flutter: 8.1.0 Not yet upgrade to the latest version. And this is the log: issue_89f38a626f952d2f99e9acd3f13edffe_crash_session_66F6A394007E000148BCF49565B0731B_DNE_0_v2_stacktrace.txt

Hi,

I have the same issue in my flutter app, In the last 7 days I received 29 crashes for 29 different users. My version is : purchases_flutter: 8.1.0

You will find attached screenshots from my play store console.

To be honest it is urgent issue, I feel like I am losing a lot of users in my app due to this crash in the payment workflow.

Thanks
