 ### Upgrade notes
 
-In order to comply with Play Store policy it was necessary to switch from using crosswalk to webview for Android 10 and above. To make this transition smoother we have implemented a migration to copy patient data and session information into the webview implementation, however please note:
+This release is largely intended to unblock the publishing of new apps onto the Google Play Store in a manner compatible with Android 10+. This release includes a difficult upgrade experience which may cause operational challenges in the field for apps with users on Android 10+. In particular:
 
 1. When loading the application after upgrade you will need an internet connection in order to cache the application code.
 2. The migration can take a few minutes to complete so after upgrade the user may be shown a login screen. If this happens, restart the application periodically until the user is logged in and the app loads as per usual.
 
-Users on Android 9 and below will continue to use crosswalk and be unaffected by this change.
+We are planning improvements to [make the migration more user friendly](https://github.com/medic/medic-android/issues/134) in a future release.
+
+Users on Android 9 and below do not need to be migrated and will be unaffected by this change. Because of this it is recommended that projects upgrade to v0.6.0 version of their app before issuing Android 10+ devices, if possible.
+
+Earlier releases are no longer accepted by the Google Play Store.
