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.

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
