I copied a newsletter that I created and published on 10/12/2017. I worked on editing a copy of it, saving it about every two minutes, for about an hour today. Unfortunately, something occurred where I had to refresh the page. It hadn't saved anything except the first thing I did, changed the coupon code. I checked to see if my iPad showed my changes as I had been working on my laptop (Windows), but it didn't. I was trying to rule out a cached page issue. Meanwhile, I started over using the same draft/copied newsletter template and after about 10 minutes of working, I got an "oops something happened. refresh the page" notification. I called in but no known issues were reported. This occurred once before but I never reported it. It seems to help to delete it and copy a template from two days ago.
