Blue Wallet is buggy for me as well. I was able to send one tip, but all other times I received an error. It also doesn’t support lnurl for receiving tips. Wallet of Satoshi works for that.
Per @shhhhpud
“You’ll have to uninstall all wallets until the one you want to open is set by default. Then you can reinstall the others. Keep keys backed up of course though”
