Hi, everyone. I have noticed that when I go to youtube on my ios/ipados devices, that they do not sync properly to other devices. When I load a video, the tab sync will still show on other devices as the Youtube landing page (not the video title it should show) until after I open another tab and load/refresh a page in the new tab. This was also a problem on Mac firefox but appears to have been fixed with the latest MacOS Firefox update. It is still a problem on iOS/iPadOS even after the latest Firefox update today. A second concern: when I use reader mode, I prefer having a light background. But when my ipad switches to dark mode (and my firefox browser follows suit, since I have it set to device theme), I notice that anytime I leave the app and come back to it, the background keeps switching back to dark. Sometimes it will switch over in the middle of reading an article. Also, changing the font will similarly revert the background color to the theme color. Thanks for looking into these issues.
