I just updated to Illustrator CC 2017, and am now experiencing severe gradient banding.

I have never experienced this issue with any Adobe app, and have been a loyal Adobe Customer for 5+ years.
I've tried exporting as jpg, pdf, almost every option avail, etc. Every export (except for pdf) shows the banding. It displays on different computers and operating systems as well.
I've spent 5+ hours on the phone live with Adobe support (sounds like they're in India). They can't or resolve, or escalate any further according to them.
So friends, I'm at my wits end. I have never experienced this problem before the update. And don't know what to do. I feel like I'm basically painted in a corner. And have no option but to look for a software elsewhere.
Anyone out there have any experience resolving this? Please help.
