When they upgraded the app recently, I opened it to zero bitcoin. The update somehow was only connecting me with new empty wallets because of a Parsing error. Even their detail logs collected from my phone weren’t showing the issue. After 2 weeks their engineers figured it out after updating the app agai n. But it was scary at first because they were accusing me of rotating keys but the issue was totally their doing. Luckily I could see two wallets on electrum but the 3rd wallet would have been gone forever if they didn’t figure it out

Ah yeah I can see what you mean by it scaring the hell out of you, it would have put me off too. I wouldn’t have tolerated being told I’ve rotated keys either, as I’ve set everything up to the spec they suggest. I’ve got my Casa multisig as watch-only in both electrum on my desktop and bluewallet on my phone, just in case something like that happened with the app upgrade but looks like you were incredibly unfortunate
