Also - I'm getting messages from stacker.news "zap on post failed". Based on my CoinOS transaction history, though, everything succeeded, and the sats were withdrawn. Not sure what to make of this.

I wonder if it's because the first one I did, I put in a really low fee (the original fee was higher than the zap). The next ones, I just left it as the original fee, and it went through with zero fees. But from the CoinOS side, it looks like EVERYTHING went through with zero fees.

Also, just realizing that I have to scan the lightning invoice even when I just post a reply! That makes sense, but it's a pain.
