I'll try with that setup, maybe it is somehow related!
Hey @Andreas_Hegenberg, were you able to reproduce it? The logout is still happening even with the user agent you suggested. Also it does not happen only with YouTube, but also with imdb.com for example.
Version: 4.889 (2024112104)
macOS: 14.7.1 (23H222)
Unfortunately not ;-( Even setting BTT as my default browser and after I deleted the floating menu a few days ago and just added it again I was still logged in to Youtube. I also added some extra code that persists and restores the cookies manually.
I'll try on macOS 14 next, maybe it's something specific to that version.
Hey @SUBZ3RO, could you please let me know if you are facing this issue again or it is solved for you? Also which BTT version are you using?
