What Just Happened

Suddenly, the entire site has changed. In ways that may make it unusable. Boards are now very small or have become so large that only about 1/3 of the board fills the screen ... requiring constant scrolling and making the board, for me, unreadable. Analysis and review has split various windows that were formally in one screen and moved them to where they cannot be seen when doing analysis. There is no longer a home page.

What is going on?

I've posted on the support thread but have had no response. I used another browser; things improved but there are still issues. Anybody know if this is a wider issue or just me? I'm not prepared to move to another browser permanently and I find Chess.com unusable on my current browser.
