We have new versions of a 2G Managed Package being released on a regular basis. There is an obvious way to notify the subscribers about new version release through the e-mailing or release notes on the public website. However, it doesn't seem to be effective enough.
What we are thinking about is to make some kind of proactive in-app notifications. You can think of it as a popup which will appear to user whenever they lands on the homepage of the app right in Salesforce. The main complexity is to make every single org which has the package installed aware about new version release whenever that happens. Displaying the notification itself is not a challenge at all.
Has anyone thought or implemented something similar? Could you please share your thoughts or the details of how the goal of engaging subscribers to upgrade up to the most recent app version can be achieved?
