If a message of full screen pops up while using the app, we recommend you enabling the app in order to use full screen.

Here we recommend you how you can do it:


Enter Settings menu.

Press "Screen".

Press "Full screen apps".

Activate or deactive switches with the apps depending if you want to use them in their full screen mode or not. In this case, you will probably have to activate the switch of Chiara in order to allow you opening the app in full screen from now on.
