App: different Devices show different modules

In the iOS version I found a behaviour, I have no idea why :
First iPhone XR schows he korrekt Sky (Garten +. SOL 11/2019):

On the second iPhoneXR the Garten+SOL 11/2019 is completely missing:

Is this issue still happening? It seems like the second device (iPhone XR) was not able to connect via WS. Are the phones connected to the same WIFI network?
