We were unable to register Flow into Powerapp if 1. we chose PowerApp as trigger, and 2. in the following action(s) we chose an action which requires an array type input, (e.g.: "Create HTML table " or "Initialize variable with type array" or even directly getting string from Powerapp and transforming it into array in the following step(s) If these conditions are met we got error message while trying to register/connect the flow to powerapp - registration failed. We tried it in 2 tenant with the same result with new and existing powerapps as well. MS O365 support team tried it in their environment with the same result. It would be nice if you can enable / fix it Thanks Laszlo
