Hello twisted5000,
On iOS platforms, there should be a huge orange button at the bottom that says 'import'. It might be hidden by the keyboard, you should be able to collapse the keyboard and see and use that button. If you still have problems it would be helpful if you sent in a report at
https://openvpn.net/support explaining your issue, a screenshot of what you're experiencing, and what iOS and OpenVPN Connect v3 version you're using. We can then look into the situation.
Kind regards,
Johan
