I'm facing an issue with my latest app where I can't connect Power Automate flows anymore. Previously, I created a flow, connected it to my app, and made changes to the flow. However, the app didn't recognize the changes. I tried to reconnect the flow, but the Power Automate menu is unresponsive. This issue is only present in my latest app, while other apps work fine. Can anyone help?
Unlike my other app, I don't have a Power Automate icon on the left menu bar. I can find it in the app when I click on the three-dot button next to the settings at the top. But since yesterday, the Power Automate menu is not responding, see the screen:

No matter what I do, the button just doesn't respond.
Thanks and best regards.
