We have some android apps that disappear from the devices on a fairly regular basis. We've taken to unapproving and reapproving the affected apps from the app details screen in the dashboard. When we do this, the app reappears on the device, seemingly with no loss of data.
Has this happened to anyone else, and have you found a way to stop this behaviour? We have an open case with the support desk which has been referred to the Dev team for investigation.
Our engineering team has found the source of the issue, and deployed a fix yesterday that should prevent future loss of app approval, as well as fix and properly revert the approval state of un-approved apps back to "Approved" in Dashboard.
There might be some limited edge cases where you'll need to re-approve an app one last time, but they should not lose their approval state again unless the app is removed from the app store by the publisher, or "All future permissions" are not granted for the app and its permission list changes.
Please let us know if you continue to face any issues!
