I wonder if you have had any complaints or experienced it yourself?
I use both this forum and as you know, the Peugeot Forum. Both forums when using the Enhanced Mobile View seem to have black flashing sections that partially obliterate the screen. If I do a refresh, it goes back to normal for a while. I am using a Samsung Galaxy S8+ with Android 8. Is this a forum software or Android issue do you think? If I exit the Enhanced View the forum behaves as it should.
