Hi, sorry to hear about the errors. The fact that you see the transactions means that cashu server is issuing the ecash as expected, there seem to be issues when the wallet tries to swap it for fresh proofs.

Please dm me a copy of audit trail of such error transaction available in transaction detail.

Minibits is still beta and last week is the first one it is under really heavy use by quite a lot of people, thus some new errors arise out of that.

We'll sort them out one by one, thanks for trying Minibits.
