-* Play Store does not show bought apps as bought
-  * this is a rare corner-case that sometimes happens on Android 10 (onwards), it's ususally fixed by issueing the following command as root on your device (or via adb shell):
-```
-find /data/system/users -type f -name 'runtime-permissions.xml' 2>/dev/null | while read file; do
-	rm -f "${file}"
-done
-```
-  * (alternatively remove `runtime-permissions.xml` from file manager as root or via TWRP file manager)
-  * reboot your device
-  * ensure Play Store has signature spoofing permission
-      * go to Settings > Apps > Permissions > Signature Spoofing and grant it
-  * go to Settings > Apps > Play Store > Permissions and grant at least the `Phone`  and `Storage` permission
-  * force close close Play Store and open it again
+### Play Store does not show bought apps as bought
+
+If your Play Store doesn't show already bought apps as bought, you need to register the device ID to your Google Account, doing so will eliminate the "uncertified" status of Play Store and thus will allow you to re-download your already bought apps. Also remote installations using `https://play.google.com` will be working again afterwards.
+* Download the `Device ID` applicaton from [Play Store](https://play.google.com/store/apps/details?id=com.evozi.deviceid)
+* Open `Device ID` and note/copy the `Google Service Framework (GSF)` ID
+* Navigate to `https://www.google.com/android/uncertified/` and login using your Google Account
+* Enter the `Google Service Framework (GSF)` ID into the `Android ID` box and tap register
+* Clean Play Store Cache (Settings > Apps > Play Store > Storage > Clean Cache)
+* Reboot your device - the status of your bought apps is now restored
