Encounter Builder issues

I've tried 3 different browsers and checked my internet connection and on mobile, and all I get is a blank page, is this feature gone now?

Since the October 7 maintenance, I have been unable to access the Encounter Builder or my saved encounters.

The pages load the D&D Beyond navigation header, but the encounter content area remains completely blank.

I have reproduced this issue in Opera, Firefox, and Chrome, including Chrome Incognito mode. Character sheets and monster listings work normally. Disabling browser extensions has not resolved the issue.

Is this a known issue, and is there an estimated resolution?

Yes, similar to @sylinrul, I've tried Google Chrome, regular and Incognito, DuckDuckGo, Opera, and Chrome on my phone. Still nothing. 

Same here.  Couldn't use it last night or today. I'm about to play in a couple hours and I can't pull up my encounters!!

Yeah, this is NOT okay.  I have a session to plan for this weekend and the site I rely upon is down!  Need at least an acknowledgement or something here.
