Yeah it’s getting on my nerves now. I have created paper wallet which I wanted to import into the mycelium but it seems iOS is literally broken. How could their developers be so lazy and not to add that feature. I’m pretty sure there are numerous ios users too who must be thinking what they have coded? Funny eh?
It has been an ongoing problem for years. People have complained and given up. Apparently there were 2 independent teams of developers. The Devs for the android app and external Devs for the iOS app. It's why the iOS app looks different from the android app.

It meant that they even no longer gave a shit about their reputation, so long as they got the money from affiliates. Best option is to just save yourself the headache and try better alternatives.
