Are some people still experiencing the YouTube An error occurred. Please try again later. ? Its been a week now and im still getting it. Fresh install of Brave is not working for me. Delete extensions, not working.
To answer your question, yes, I get that fairly often of late: maybe 2-3 times a day on the bad days, zero times on good days. However, it usually goes away fairly quickly and the video plays. I assumed that it was due to the shear number of people using YouTube due to the lockdowns all over the world, but that is an assumption. If anyone is sure this is an issue only with Brave, hopefully they will share that.
