Same thing happened to me. First time it got hung up --- the progress circle ⭕ didn't complete. 

The second attempt, the progress circle completed, but the zap ⚡ indicator did not illuminate. 🤔 

 Yeah - although I see different zap indicators in Damus. I’ve noticed that they still go through; just don’t get “registered” properly via the nostr client sometimes. 🤷🏻‍♂️
