Cant control Shelly remotely (connected to wifi)

First time user of Shelly and it works great when my phone is connected to the same wifi. However, when I am outside I cant control Shelly. I dont understand why, I can see in my router settings that a device named Shelly is currently connected also.

I tried rebooting it without success.

Yes, cloud is enabled. Tried disabling and enabling it also.

Zitat

in App or WEB-UI? Try to enable Cloud in App

I tried both now.

It can control the relay remotely on my laptop through Chrome, also through the browser on my Android phone, but on the same phone and connection, it does not work on the app.

So I guess its something strange with the app.
