Have you recently switched to a new smartphone and your premium upgrades or settings are not showing up? Purchases are handled entirely by the app stores, so this is almost always a temporary store connection or account issue. Here is how to fix it step-by-step.

1

Check Your App Store Account

Your licenses and purchases are directly tied to your app store account, not to your physical phone or SIM card.

You must log into your new phone using the exact same Google Account (or Huawei ID) that you originally used to make the purchase. If you use a different account, the app store will see you as a new user and will not unlock your features.

2

Check Your Installation Version

Depending on how you originally upgraded, you might need to install a different version of the application:

Standalone App (aCalendar+)

If you bought the separate premium app named aCalendar+ in the past, please make sure you actually install the paid aCalendar+ app from the Play Store on your new device, instead of the free aCalendar version.

In-App Purchases

If you used the free aCalendar version and bought upgrades (like Business Features) directly inside the app, download the free version again. The system will automatically restore your purchase as soon as the Google Play Store app correctly syncs your licenses in the background.

3

Refresh the Google Play Store

Sometimes the local Google Play Store app on your new device gets confused or uses old cached data. You can force it to check your real purchase history again:

1

Clear Play Store Cache

Go to your Android phone settings → AppsGoogle Play StoreStorage and tap Clear Cache (and optionally Clear Data).

2

Force Stop the App

Go back one step and tap Force Stop to completely shut down the Google Play background services.

3

Reopen and Restart

Open the Play Store app again so it refreshes online. Afterward, restart your smartphone and check if your upgrades are now recognized inside aCalendar.
