I don't know if this a mint error (something might be wrong with his mint) or the wallet. Hard to say, if you can reliably reproduce it, I'll fix it! Would be very grateful for that!

Happy to try 🤙
Screen capture video, image, description… what’s best?
Video with a clean wallet state (delete local storage before) would be best! Thank you, I appreciate
Got two different errors
The image was that same “mint error” again. I hit “swap” and then switched mints.
The second attempt to replicate (video) gave a new error.
Then it left the display with both mints showing 54 sats apiece (the other screenshot). When I refreshed, those corrected themselves but it was funny to see.
Hope these are useful
