I use Signal on a google-free LineageOS device, installed directly from the official apk. For a couple of months now, I'm struggling with disappearing messages. Sometimes it's just individual chats, sometimes all of the chats at once, and I have no idea what to do about it. It seems to happen mostly (but not exclusively, and not always?) after phone reboots and/or after the Signal backup process ran. Most of the time, messages that disappear from the phone are still synched to the linked desktop app, so it's most definitely a phone thing. When it's individual chats disappearing, I couldn't find any pattern. Sometimes it's older chats, sometimes one of several from "today's chats." A Signal re-installation and restore from backups didn't help. I run LOS 20 on a LG G5. I believe the pioblem existed already on LOS 19, but not as severe. Any ideas to what I can do? :boost_request:
