Have you tried creating Flows from within PowerApps? Did you need a couple of attempts to get your flows right? Did you delete your unwanted flows?
Well now your app is messed up!
Here is the walk through of how to mess things up!
I’ve created an app with two buttons both calling a Flow.
Then I created two flows triggering by an PowerApps button
Then I exported my PowerApp ( one day this might become useful!)
When I look at my PowerApps app details I can also see two flows.
Time to delete my second button and my second Flow.
Then I tried to export again. Ai, this is where the trouble starts
An ugly “The Provided flow ” has been deleted” warning.
Looking at the app details the removed flow is still there.
I went through a couple of attempts to fix my export file, but it is quite likely if you get this far through this post that you don’t have an export anyway. The advice is start over again with your app or accept that you can export the app. Depending on the number of people running into this issue I might attempt fixing export files.
