Z Fold 4 - Big screen not ported to small screen when closing

[4rings]

Hi,

I've had my Z Fold 4 for a few years now. Whenever I was doing something on the big screen with the phone open, and then close the phone, I would be able to continue with whatever I was doing on the small front screen. This no longer happens since the phone upgraded to Android 15 a few days ago. Very frustrating. Can anyone help me fix this please?

Thank you.
