If it worked before and you didn't make any changes, I would work with TAC.
Have you configured Airgroup for your Chromecast devices?
I think in a different post you mentioned that you only see half of your clients in the MM; possibly the ones that are on one of your controllers. That indicates that there may be an issue in the communication between one of your controllers and the MM, and that can also have an effect on AirGroup. I would recommend to first address that issue before moving to this Chromecast issue.

Subject: Chromecast not working
Hi,
I've tried many solutions found on the web. It was working before christmas. Chromecast devices aren't working anymore. Clients and Chromecast are on the same VLAN.
Thank you
