Ok so here’s what I found. I deleted my NWC connection and selected Zeus as my wallet in my Nostur settings. If I try to send a zap by long pressing the zap button on a note then it seems to think NWC is still connected. But if I just tap on the zap button on a note, then it launches Zeus and I can send the zap. So it appears to be an issue with long pressing the zap button.
