If tapping "Restore Purchases" doesn't activate your upgrades, try the following:
Clearing your cache
Before reinstalling, you can also clear your cache beforehand.
5. Afterwards, open the app then tap "Restore Previous Purchases
Reinstall the app
Sometimes the best and easiest thing to do is uninstall and reinstall the app. Tap and hold the MyRadar icon on your homescreen, then reinstall the app from the Google Play Store (Note: if you lose any favorite locations you have pinned on the map)
When all else fails...
This process will ask you to uninstall, then reinstall the app through an internet browser on your computer. Note you will need to use an in-private/incognito window for this process to work:
1. Delete MyRadar from your Android device.(You may have to restart your Android device after deleting MyRadar to ensure the Google Play store registers it as uninstalled on the device)
2. Open an incognito window in the browser of your choice.
3. In the incognito window, log in to Google Play with the e-mail address originally used to purchase, on the desktop/laptop.
4. If you downloaded MyRadar, open this link: https://play.google.com/store/apps/details?id=com.acmeaom.android.myradar
(If instead you downloaded MyRadar Pro, open this link: https://play.google.com/store/apps/details?id=com.acmeaom.android.myradarpro&hl=en_US&gl=US
5. You will then see a green button that says "Install" or "Installed", just tap that button and select the device you would like to send the app to.
Persistent upgrade restoration problems (in the case of multiple Google Play Accounts)
Unfortunately, this issue, while rare, seems to be a rather persistent problem for many apps available on the Play Store. In our discussion with our engineers and Google's Play Store customer support teams, this inconsistent purchase recognition behavior stems from how the Play Store handles verifying upgrade licenses when there are several accounts signed into the Store at once.
We've searched extensively for a resolution to this very stubborn problem, and ran into a lot of similar reports across the years (see here and here) that points to this problem being on the backburner in Google's development road map for the time being. Unfortunately, this severely limits what our engineers can do to resolve this issue permanently, as we do not have the manpower nor storage space to safely and securely hold the amount of user information needed to host purchase license verification independently rather than through the Play Store.
While this is largely out of our hands, we have found that there is a higher chance of success getting purchases correctly verified if you reinstall the app through a computer, as seen in the previous troubleshooting procedure. Frustratingly, a clear fix for this problem is largely out of our hands.
As we continue to increase in scope and size, our engineers hope to be able to tackle this problem in new ways down the road. While there is no ETA for any fixes that would resolve this problem, our engineers are always working on improving the app's reliability and functionality.
Our technical support team can issue a refund for any upgrades within 60 days of the time of purchase. We share any frustration felt over this issue's complexity and persistence.
