I have bought Enpass Pro on Android and IOS while using a free windows store version on my PC. After a latest upgrade I created my enpass account through the PC version with one of my email(call it email1 here). Now email1 account is a lite account. How can I change it to a Pro account while I don't want to register with a new email on my Android? Would it be OK if I just login on my android phone with email1 account and the app could recognize and convert my account status? Hope for replying, thank you.
