No history available and no option to select version 3.5 or 4

Hello, when I logged in today it showed “upgrade to plus” and no option to select the 3.5 or 4 versions. Also, the history is not appearing on the left tab. I have already subscribed to the Plus version and have been using it for a few weeks. Is the website or server down? Is anyone facing the same issue?

I tried logging in from different browsers and cleared the cache, etc.
