@Willieb Don’t use apple backup. Just create new wallet on desktop and backup wlt file, and private key yourself in safe place. Desktop nanowallet guide you step by step what should you backup.
Wlt file = wallet file??? I’m not tech savvy at all haha
Yes wallet file 
it has wlt extension. Try use nanowallet should be no problem
Is the trouble of secret key corruption planned to be fixed by next IOS wallet?
Should I upgrade the current broken Wallet app to normal version?
Also, when will the next IOS Wallet be released around?
There was also a case with the coin check
Looking at NEM Foundation people and Minarin’s actions
I truly respect it. This Wallet problem surely solved
I hope they lead us.
