While using an iPhone 13 (IOS Version 17.6.1), I was switching between a game (that was in landscape mode) onto Brave Browser (which registered in landscape mode) and the Brave Browser displayed a strange landscape video preview (nothing I had historically displayed on the browser either) as the preview between the windows, rather that what I thought I would usually see as the preview between the windows.
Closing and opening the app would not fix it, only deleting and reinstalling the app worked in fixing the preview issue.
Thought I would leave the feedback and prompt a fix!
