Microsoft Teams Flow Bot issue

[NativeNass]

Hi everyone

Since earlier this week I have a problem when using the following option in my flow:

Whenever I get a teams message from the Flow bot to select one of the previous options, i get the following error:

"Cannot reach the app. Please try again".

The problem is that my invoicing process does no start, since i cannot seem to connect to the Flow bot.

It is the same issue on the App and the Web version, when I open the Teams app on my phone, it just get a blank field without option:

thank you in advance.
