Hi! Are all requirements satisfied? From https://faq.whatsapp.com/419827870318306

There are a few reasons why you might not be able to see someone's last seen or online:

• They might have set their privacy settings to hide this information.
• You might have set your privacy settings to not share your last seen. If you don't share your last seen, you can't see other contacts' last seen.
• You might have been blocked.
• You might not have chatted with them before.
• They might not have you saved as a contact.
• You might not have them saved as a contact.

Have you subscribed first? https://waha.devlike.pro/docs/how-to/presence/#subscribe-to-presence Last seen will be updated only when the client (the session) actually sees the participant online. So if you request that information right after you session started - it can be null, totally fine. But if the session sees that person online - it remembers the last time in lastSeen field. No way to get that information for person who the session never seen online (but before to subscribe https://waha.devlike.pro/docs/how-to/presence/#subscribe-to-presence)

Thanks a lot! I will do more test on this.
