It's a instagram-like client for nostr. I recall they have a slightly different payment system which might have explained why you were seeing incoming zaps and nothing in your wallet. Inconsistent standards will always be painful. That said, I saw below that you used to have a different address @npub.cash so maybe your zaps are there. If you think funds are going to the wrong place, make a small change to your profile and republish. That should help everyone get your latest details hopefully.
