Happened to me as well. Update minibits (OTA from within the app) and re-recdive the failed payments (click ok them and then the button). nostr:npub1kvaln6tm0re4d99q9e4ma788wpvnw0jzkz595cljtfgwhldd75xsj9tkzv might be able to help.

Yes, that works, was a bit annoying having to reclaim one at a time, but worked, maybe some sort of batch reclaim option can be a good UX improvement
Thank you for the report. The issue relates to recent mint upgrade and should not repeat anytime soon. Glad the prepared reclaim path worked for you.
