‘As @Anton Mefodys, has advised above, it will be fixed in MR2 release, late October/November 2020.’ You wrote that 26 days ago. It’s now the 4th of November and still no fix. Could you please confirm when this will actually be fixed?
I’m using the latest version of Firefox (82.0.02 64-bit) and this issue is still happening with YouTube. I cannot log into my account or see my saved likes or history even though it appears I am logged in initially when I open YouTube. But once I go to either my channel page, liked videos or history YouTube then keeps asking me to log in but when I do I just get redirected to an error page which says, ‘405. That’s an error. The request method GET is inappropriate for the URL /youtubei/v1/browse. That’s all we know.’ . I have anti banner switched off just for YouTube. It has been like this for over two weeks now and I’m having to use IE to access my YouTube page. When will this issue be fixed? Thanks.
