I had an issue with a flow not working properly when called from powerapps. I created a new one. I removed the old and attached the new. It no Worked fine for me.
Strangely - I have 30 sites access the app at any one time, 3 (could be more) are reporting the flow does not work as the task fails. My research shows they are calling the old flow. I have had them clear cache on their PC browser, reinstall the app on the tablets yet they still have the problem.
I then put in a function that tells them the version they are using. All report the same as me. Can anyone shed light on this problem and give ideas to try.
