"Page is not yet created" bug

Hey folks, 

Huge brizy fan here! Love what you folks are doing!
That said, I see a lot of people having the same problem that I am having - the whole "page is not yet created" thing. I've cleared my cache, but no go. I've tried separate browsers (Chrome, Brave, Microsoft Edge)....nothing. I've gone from draft to publish to update to save to publish to draft to publish...every status combination you can think of, and none have worked. I've built a few websites in Brizy already (have been doing so for nearly a year now), and this is an issue that has frequently come up. Sometimes it is fixed with a new browser (not always), sometimes it is fixed with a cache wipe (not always)....but every now and then, like this time, neither seems to work.

The page isn't even finished (not even close!), but I find that pushing out preview views is a really valuable way for me to check embeds and such, and having this issue pop up on practically *EVERY* site I work on, and having my family (they have their own Brizy accounts) facing the exact same issues, is always a hassle. 

Is it possible to
1) Look into the site? Latest example is here: https://grapefruit6733753.brizy.site/


2) See if the user experience can be improved in such a way as to reduce the volume of recurrence of this (or simply eliminate this issue) in the future? [I can see that this seems to be a very common issue in the Brizy support area; and certainly I imagine the support team would be able to put their time to better use than telling another 500 people to delete their cache or try incognito browsers :D).

Thanks, and all the best!
