Yes, this has been an ongoing issue for me with GD for sometime. If you turn off ETP(see screenshot) it should work. Also, look at the third party cookies that may be blocked.

The cookie list keeps growing, but not working for me.

You get the third party cookie error? I'm not noticing any problem in a test profile (regular window / default settings) with: individual PDF, individual JPG, zipped PDFs, zipped JPGs. I wonder what the difference is.

Yes, Here are screenshots of cookies allowed, but still blocked.

What's funny is that I got the same 3rd party cookie blocked in Chrome, but after allowing the cookie Chrome worked. see screenshot
