CC Libraries import yields progress indicator for thumbnail
With the most recent release of Illustrator (23.1.1) on a Mac running Catalina 10.15 Beta, any time I drag an item into the Libraries panel, a thumbnail fails to appear (instead I get a persistent animated progress indicator). I'm able to see the correct thumbnail of the imported item in other Adobe apps (Photoshop and InDesign), as well as online (Libraries --> View on Website). Only after I restart Illustrator do they appear.
I have very similar problem but the problem does not resolve when I reopen the application.
Latest Ai update, latest OS (Catalina). I had to reset the application. It resolved the issue for items I had added to the library previously but it happened again when I added a new item. Thanks, Ric
