When I attempt to add a new theme to Adobe Color using the "add button" on the theme pallet in InDesign, I get the error message: Unable to add theme to Adobe Color. I've seen the problem posted on several forums, but no answers. Can anyone point me in the right direction?
There is no answer because there is still a bug in InDesign CC 2014. The feature is working for some, not working for others. We may have to wait for a new version of InDesign for it to be fixed. Based on what Adobe said last year, we will have InDesign CC 2015 coming this year. No announcements have come, but my guess would be this summer.
Incidentally, I have the same problem on two Macs. I've reported it to the engineers so they know it's a problem.
