We need to associate your subscription with an account and email, so you can always re-gain access, and also be able to use Pro on any device by simply logging in.
You will be prompted to create an account right after the subscription checkout. It's a very simple process in which we only ask you to create a password and optionally save your name.
You haven't finished this process, please go to Settings in the app you used to subscribe to Mate Pro — there should be a Finish Sign-Up button.
If you don't see it, please contact us at firstname.lastname@example.org
