Slow performance since 1.6

Hi

Experiencing an ongoing issue with Nucleus + and Chromecast Ultra’s

ROON display was previously frozen in time till the last 1.6 release, then I had circa 14 days of no issues and a fantastic user experience. Then suddenly on the 10/05/2019 - Frozen in time with no troubleshooting actions resolving this issue. To troubleshoot the following steps were taken - Reboot Each Device via unplugging power, restart via Google Home, restart of Nucleus core… nothing is working!!!

Any insight into what changes could be causing these issues with ROCK (i.e changes to the SDK, Cast Application Framework, etc)

Many thanks

Mark
