Could it be an issue that I am from Poland and not us? My friend had the same issue, but on all forums the problem is non existent

I'll look to it. It may be a valid option. Thank you very much

I too used grapheneos for a long time, but WhatsApp just give me a message about WhatsApp being unofficial, and I downloaded it form Google Play, Aurora and official web site on different installations. I tried to start it from backup, but the problem persisted.
