Hi there, exactly the same issue here, since the beta 1. I dot not have Firebase but custom php backend. It’s still happening with the beta 8, I filed a report but no response in two months. I try many modifications but no luck on server side. I have +100K active users on app iSoft, I fear the iOS 17 official release.

Hi again, Finally, if you remove the "id" parameter from the payload, it seems to work for every firmware. But I loose the rich media within...
