You are in good company. PowerSchool (formerly owned by Apple) had their Schoology app removed from the Play store last week. I don't know they details, but they are big enough I'd kind of expect them to get at least a conversation from Google instead of just removing their app. What has happened now is that other applications have been released with the same name and students & parents are downloading those apps and typing their names and passwords into them. Whatever security Google thought they were achieving by removing the app seems unlikely to have been greater than the risk they created by the removal.
