I find the same thing. It works... but the connection times out a lot. I can make a payment and as long as I keep the screen open it's fine. But if I close the iphone screen for a while I have to 'reconnect' and it's definitely annoying.

I could turn off TOR (this is a 'remote'/server node) but the app literally recommends Tor or a VPN on the iphone for privacy. What do you guys think?
