Use a consistent source
Return to the store or publisher source you used to install the app. Confirm the app identity before accepting an update. An unrelated advertisement that says an update is required is not enough reason to install a file.
Read what changes
Check the release information when available. Look for changes in device requirements or features that matter to you. A directory’s version label is a useful reference, but the current publisher listing is the place to confirm availability.
Keep account recovery in mind
Before changing an installation, make sure you understand how the app saves progress and how to sign back in. Do not uninstall an app simply to solve an update problem unless you have checked the publisher’s instructions.
