@RyanRules1 thereās no ability to get version data with Forge apps: No API available to get app version for Forge Apps?
If there was the ability we could very easily show the users an āupdate app to continueā message to block all functionality until they updated.
Although since Forge app versions are bundled and immutably held for ransom on Atlassianās slow infra, you could only do this for future app versions. So it still needs an external trigger option in the Developer Console.
[edit] Theyāre finally listening: An update on managing App Versions on Forge
