So I have had encountered these problem numerous times in the designer.
Sometimes it wont let me publish a page, and the publishing doesn’t work and I have to refresh the browser in order to publish. Auto save feature is working
Sometimes the auto save is not working but can publish. Sometime this fixes itself without refreshing the browser.
Current issues, as I am posting this. Auto save notification turns to a wifi signal thats red. Changing Pages in designer will not load. I need to refresh the main browser in order to fix this. Resulting in losing any changes I made before noticing that it is not saving. Extremely frustrating trying to go back and figure out where the changes I made stopped!
