Agreed. It stops saving changes but I can’t tell WHEN it stops saving until I try to exit. I then have to refresh and re-enter the campaign builder to find out exactly what was saved. After that its only safe to add 1 or 2 items at a time before closing and saving again. It becomes painful to work with. I’m even trying to find ways to shorten my campaigns to avoid this, which is not a good thing.
I’m going to try to logout and delete cache to see if that changes anything going forward.
