Tested heavily and no dice. Mobile off or not online my payments to that account would not go through, perhaps I have missed something but that was my experience a month ago and with two different mobiles.

I saw you guys just made a theme update that looks amazing  plus some changes that should improve the wallet functionality, will test it again, really liked what you guys are building and you are clearly working hard on that wallet, additionally, you are very responsive and present here in Nostr, that is very much appreciated, you guys rock!
