Flow with myStrom-SmartHome and Wifi Switch V2

Hello all
I recently have the problem that I can no longer enter the temperature when testing the flow for the app myStrom-SmartHome and a Wifi Switch V2.
Does anyone else also have the problem when a new flow is created?
An old existing flow continues to work correctly.
Greetings Daniel

Found out the problem
The problem only occurs with the app on iOS.
The flow can be tested without problems via my.homey.app
