When I watch a video in YouTube with the sound on, the sound stops when I open full screen. So it seems it is not possible to watch a video in landscape with the sound on. Where can I find a setting to repair this?
I think this was the same problem I had - the cause was the option:
Settings - Sound & vibration - Do not distrub - "Auto turn on in immersive mode"
Switch this option off.
This option actually makes no sense to me and it seems it might even be enabled by default 🤷
Yes! I found it. And it works! Thank you so much!
