I've had a broken Signal account for like a year. I migrated from an older phone and the process didn't work because apparently the version of Signal I had on the old phone was "too old" or something? (why didn't the new destination phone's copy of Signal tell me this?) ... I've been waiting, hoping they fix the issue where I can re-register my phone without having to delete the app and lose all my message history with photos from family etc. For a while, I could receive messages but not send them (yes, seriously). Recently a "re-register device" button appeared, but when I try to go through that process, I get the SMS with the verification code, I enter it, and the app crashes. Now I can't even access the message history because the app forces me to resume the "re-register" flow, but it doesn't work. I'm holding out hope that yet another app update will eventually fix THAT crash and I may indeed one day be able to use Signal again. Not that I want to, I'm not impressed with my experiences with it. :\
