Maybe the total balance didn't update yet.
This doesn't make sense, you should have received 100 sats on nostr:npub1cm3rpgj7457yjuqnvdalxaauakqu0ndkpkyp5cldkyutpz4xszpsmk96wt. Did you try to restart Blitz?

This was a fresh wallet with zero balance so any change in the balance came from this transaction. Any idea why it only showed 36 at first, and then changed to 100?
Probably a minor bug. I reported to the dev here, so he can fix it: https://github.com/BlitzWallet/BlitzWallet/issues/397
