I regularly receive a notification from GmsCompat with message "Action required in Play Store".
When I click on it, it offers me to install "Google Play Services for AR". I always deny the installation because I have no use for that app. However, it keeps notifying me multiple times a day for the same reason.
It's unclear to me if this is coming from the PlayStore compatibility layer directly, or from some installed app I have on the device.
I'm interested if others have observed the same behavior, whether this is expected and whether there are any work arounds.
PS: It might be useful to have a forum tag for the Google Play compatibility layer
