As of today (3/12/24) when I create a new PowerApps app, I can no longer select existing Power Automate flows to add. Yes, my flows have been shared, Yes, I can see them in apps that I have created in the past. I have had others in my org try and they are experiencing the same issue. I am able to create new Power Automate flows from within Power Apps just not able to select shared flows any longer.
Steps to reproduce:
- Create NEW power app (I did canvas, tablet)
- Click on Power Automate icon
- Click Add Flow
Under "Add a flow from this environment" you should see a flows that have been shared and are compatible with Power Apps.
