Hmm interesting, no update or anything just was working then stopped? Are you on the newest, I updated nostr-sdk but I've been running it and working as far as I can tell just checked with damus. What log level are you looking at if you change it to debug is there more info? There are two debug logs after the pay index is incremented, if it can't decode the zap request and the zap note that is created that could be helpful
