That was my issue as well, it would just grey out. Once i started a new landing page everything seemed to be working properly. Definitely on the Marketo side. Very buggy yesterday.
It rehappened since. In all cases, this occured after having updated a series of landing pages but those times I either just had to close window and re-open or updates were saved anyway, even if there was no auto-saved status.... spooky
If your page is stuck on saving, try making another, very minor edit (add and remove a comma, for example) on that page and give it a bit of time to update. It worked for me a few times.
I've been seeing this same issue today and many times during the last few weeks. If I wait about 5-10 minutes it (usually) finally comes back to life and auto-saves, but it's a huge productivity killer. Don't know why they can't have a "manual save" override button.
Same issue here. It seems to have gotten worse lately.
I am on 11 minutes waiting for it to save for the page that I am editing right now.
It is extremely annoying to have to close it and re-do all of my changes. I have to set aside much more time than should be necessary when I have landing page work to do.
