Same with me. Logging in and out doesn’t fix it. Movie history loading but not TV. That seems as to be causing the issue.
I’m almost certain you’re seeing a different issue unless it’s the same error message. Can you share a screenshot?
You’ll need to be more specific. This issue that results in ‘Bad Request’ errors is almost certainly different to whatever you’re seeing. Hence why I asked for a screenshot (or a screen recording would be better) of the error + logging out and back in causing the same error. If you’re seeing other errors, they’re unrelated and please create a separate post.
I’ll let someone know about that issue, but it’s separate to the ‘bad request’ issue.
