While adding a flow to onSelect function for a button ,
Action-->Flow opens a Data window and this window is not scrolling to select the flow. It is listing first few flows.
On the List of flow window ,scroll bar is not showing up.
For the current Power app version 3.19014.8
This is a stupid problem... wow.
One semi-workaround... go to portrait mode, and scale thescreen down all the way down to 100%. This will give you lots of vertical to find your flow. This has GOT to get fixed. Its an inexcusable inconvenience!!
