I'm so sorry I can't give a more concrete solution. The tests I do and the reports from Google's Play Stroe tell me that the app should run correctly. I don't have the devices you're telling me, so I can't do concrete testing. Again, I'm sorry. I've tried iPhone 6 and iPhone X and by holding down the code, it is selected completely and I can copy the whole code. Can you try it, please? It's to rule out some problems. Thanks.
