Ok, it seems that swiping on the left side is sometimes triggering "back" a second time. On the right side this never seems to happen.
As you said, it must have to do with the built in swipe function. Oh well 🤷🏻♂️
Interesting! It depends in which hand I'm holding the phone, so I'm swiping on both borders. I will observe if it happens only on one side of the screen. Thanks for the input!
On my TV I'm using Smart Tube Next It's really great! But on my phone I have no idea...
