So there is now simply a black area where the notch is? Yeah, that's what I was hoping for. It's an easy fix, I don't need to re-design the whole game.
I didn't change Viewport Fit and Fullscreen mode. What I did was removing construct-mobile-notchfix plugin from the export. Export to Cordova, remove plugin from the config.json and config.xml, then zip and build an apk with C3.
Thank you so much for your help!
haha you solved the problem mmmm ... you should buy me a coffee :p
