I have to keep refreshing the browser in order to edit my client's 7.1 site, anyone else with the same problem? It doesn't happen on my other SS sites. It's very annoying and is slowing down the build and editing process massively.

Log out & try again

or try other browsers

Yep, I open a second window/tab incognito, so I can see the changes. Or I use two laptops, one to edit, one to view.
