I moved some satoshis to a Cake wallet for easier spending (no hardware needed). Now I’m getting and error that is preventing me from sending from that wallet. Super convenient. I understand why so many non-tech people see Bitcoin as a joke: when the tech works, it’s strange and obscure; when the tech doesn’t work, there’s nothing to do but shrug and wait…

Being quite honest I’ve never heard of this wallet. If you’re looking for a good phone wallet I’d recommend using Phoenix Wallet. You hold the keys and it can do both lightning and on chain payments.
As for this wallet, it might help to #asknostr for a solution.
