I apologize you're unable to edit your campaigns as easily as you should! What browser are you working in? Is this happening with more than one browser or even a private/incognito window? We always suggest first testing your browser in case this may be connectivity related or caused by any 3rd party add-ons. Also, are you working with templates that you copy and reuse often? We have seen cases where copying and reusing campaigns in our Legacy templates over a long period of time can carry over problematic formatting. Because of this I would suggest inserting your content into brand new blocks instead of blocks that are being copied over. You also have the option of moving over to our Third Generation Editor. Do you have this same experience in this editor?
I'm having the same delay problem. I've waited up to 9 minutes to get a response to my 'save' command. The frustration is indescribable. I'm on Windows 10 using Chrome and Firefox. Firefox seems to work best.
Mine is a huge, weekly project of updating a calendar of events. It is a 1-column table with 60 rows. It's very classy with lots of graphics, colorful, lots of hypertext links. We do copy last week's calendar and then proceed with changes.
Even if I migrate to the 3rd gen template, is this project just too big for your platform? If you want to see the project... www.calclane.org/weekly-calendar/.
