Alright, I just zapped both of you. I then open cashu me, default mint is minibits. Nothing happens.

The wallet must be open before you zap, it doesn't look back into the past. That would be a super simple switch to flip though... probably useful given the deadly nature of being a PWA in the background.
Yeah it's on the same phone so it should look back at least a few seconds, or maybe a whole day so I batch my zaps.
