We need the ability to get various metadata about the app using formula. For example it woud be great to display the version number and relelase date of the app rather than manually adding them in a text field.
I'll be showing this in a video tomorrow here: https://www.youtube.com/watch?v=vD2bhi-q_Q8. In my testing, it looks like you can use the Power App for Makers connector to achieve a piece of what you're looking for. For example the below will give you the publication date of the app.
"App Published On " & PowerAppsforAppMakers.GetApp("ecd50b93-4a13-45b7-bb15-af8a8ed946ab").properties.appVersion
The following will show the last time the app was saved (but not neceessarily published.
"Application Modified On " & PowerAppsforAppMakers.GetApp("ecd50b93-4a13-45b7-bb15-af8a8ed946ab").properties.lastModifiedTime
You can use this to see if the version you're running matches the publication version. I'm still testing a few things before the video tomorrow but I wanted to share the code I have found so far since it's not especially documented well or correctly.
Lord knows it's not perfect and doesn't get 100% of what you're looking for. That connector might have other goodies I'm not seeing but after looking at it all night, I'm struggling to see the full version info even though there is a PowerAppsforAppMakers.GetAppVersions which feels like in the ballpark.
