In the rare case that myatmo 'Premium' deactivates although the expiration date has not been reached, please do the following:

1. Delete myatmo from all (!) your devices - this is important
2. Restart all your devices
3. Reinstall myatmo on one (!) of your devices, ideally on the device where you observed the drop of the 'Premium' expiration date
4. Restore Premium on that device - you can do that by tapping onto the appropriate button on the myatmo 'Purchase' screen
5. Once restored, create a screenshot of the purchase screen with the expiration date and the device ID on the bottom of that screen visible
6. Reinstall myatmo on your other devices

If you still experience that the 'Premium' state deactivates, please create a ticket and send us the screenshot you created in Step 5. You may also want to try restoring the 'Premium' expiration date on your other devices. iCloud will then be forced to sync the date properly sooner or later.

Attention: Make sure that the screenshot shows the expiration date and the 'Device ID' own the bottom of the captured screen.
