Could you dm me an audit trail of the first transaction where you've got "proofs pending" error? Should be a lightning transfer.
Message "proofs are pending" is returned by mint in case lightning stays in-flight.
Wallet normally keeps such ecash notes reserved to settle the payment in ending state as well and moves them back o spendable balance only when mint confirms that related payment failed on lightning side.
If you get this error, smthg broke, could be on the mint side. with an audit trail I can check mint/lightning node for specific payment status.
