I assume you’re zapping from an attached wallet since that would explain it:
In the last release, we removed the toasts and used optimistic updates for non-custodial zaps so it immediately looked like it succeeded while the payment was attempted in the background.
However, a bug in this optimistic code broke replies showing up so we had to remove this immediate visual feedback. So I think that’s what you’re seeing: nothing because the payment is still pending. Do you see pending payments in your wallet logs on SN?
While writing this I got an idea how to fix this missing feedback in a way that doesn’t break replies.
