Cannot Save Favorites from Stock

I cannot save a stock image as a favorite. I have tried the following: 

1. Logged out of adobe on all devices

2. Tried different browsers

3. Cleared caches/history in all browsers

4. Renamed libraries

5. I am under the 1000 asset mark not just on My Library, but across all libraries

I have plan credits and can download images, but I cannot save favorites which I would prefer to do before making a final decision on which to license. 

I've reviewed the threads here that mention the issue, but none have worked. 

I am using the stock website, but it won't save from CC either.
