So, curiously, after reading your question, I checked notification settings, both on my Graphene OS and on my Minibits install... Both places, notifications were already enabled; and so I made no changes; however, mysteriously, now my zaps are working?🤔

Thanks for the prompt to check that...

I'm hoping to find a solution to the invoice error before leaving for bitcoin2025... But I'll have to find a new invoice.😃
