I’ve seen this reported elsewhere, but nothing has been seen here in the community.
I tried versions 7030 through 7033 and got the same results.
Some are blaming Streamfab 7033, but since it seems to go back to at least 7030, there definitely seems to be a change in the Tubi website.

When I get time, I will look at the log and see what that might say, but this was with the temp folder, etc., cleared as well.
It also seems Tubi won’t stay logged in. Although you can use most of Tubi without logging in.
LOG is under Details below
