Mobile Friendly Checker Not Working

Mobile Friendly Checker is not working today. Yesterday it worked fine.

So its not just me. I get this pop up: Reference #3.ece1ab42.1496428642.42db240c

It is a pain, because a window, the same size as the one that pops up when it is working, does not have a close x button to close it, so when i click back, it does not go back t7o the draft - so I click refresh, which takes me back to the draft.

I concur - mobile checker is not allowing upload of markup. Good thing we have google's mobile checker.
