Here are answers to common questions: how to subscribe if the payment does not go through, and what to do if the subscription was not restored after changing phones.
How to subscribe · Subscription is not restored · Moving your data
Users in Russia can subscribe via RuStore right in the current version of the app — there is no need to reinstall the app or move your data.
If the payment button does not appear, make sure you are signed in to your RuStore account and tap "Try again" in the subscription window.
The app is distributed in two versions — from Google Play and from RuStore. They are separate apps, and a subscription works only in the version where it was bought. It cannot be moved to the other version.
If you subscribed in one version, keep using that version. On a new phone:
To check your app version, open Settings → "About app". The store name — "Google Play" or "RuStore" — is shown next to the version number.
If you have already installed the other version, move your data to the required version with a backup (see below) and uninstall the extra version.
Features purchased before the subscription (one-time purchases) also work only in the app version where they were bought.
