Howdy, after days of trying I could not port about 2.5 GB of Signal chat history from my old Android to my newly flashed Pixel 8.
The 'direct WiFi' failed every time (even though the phones connected to each other) and the attempt to 'restore from back-up' was thwarted by Signal being unable to restore back-up from a newer version.
Sure enough, the newest version of Signal I could install on the Graphene was 6.41.3, but the old Android was running 6.42.3.
Has anyone else resolved this challenge recently? Advice gratefully received!
(I did not manage to reinstall an earlier version of Signal on the old phone, and was getting snarky messages from Signal bots for requesting too many SMS verification codes in a short period of time!)
