X is urging users to follow the non-existent account @twittersupport at https://help.twitter.com/en. And pending message requests can't be dismissed.

• https://help.twitter.com/en tells me to follow the non-existent account @TwitterSupport. Needs updating. I'm encountering a bug and can find no way to report it, short of going to HQ or GitHub, so I'm resorting to the latter.

• Aside from that documentation issue, I'm encountering a bug, as I said. Specifically, https://twitter.com/messages shows 1 pending request even though I've blocked the user. Re-blocking over and over has no effect. Refreshing has no effect.

• Staff working for @ElonMusk, please fix or at least acknowledge these issues. OK?

Still stuck in status "pending request" after blocking the sender.

WORKAROUND for 2nd bug: Report it. That deletes it and gets rid of the pending request.
That leaves issue 1 and 3 still open.
