Seems to be a new issue. After changing page you get the black / white screen of death, which after many seconds resolves to the new page.
It’s also very slow when you create pages.
Hi @raelyn 
I see you reported this in the support app. Thanks a lot for doing this!
All seems ok on our side on the infrastructure side of things and when we open your project.
The team has been in touch requesting more information. Can you check it out and send it to them so they can investigate further?
Okay! I can’t view any of the pages in editor now.
Ok that’s weird. We are talking about this project, correct?
Sorry, I’m blurring the content because I noticed you have done so in the past when posting in the community but hopefully it’s enough for you to go on 
A couple of things you might want to try:
- closing the browser and opening it again if you haven’t closed it for a while
- if you’re on Mac, looking at the Activity monitor to check if you’ve run out of memory and need to restart your computer (can happen if you haven’t shut it down for a while)
