MR60 Mesh and Chromecast

I have the MR60 Mesh network & a house full of Chromecast devices.  I purchased the MR60 system in anticipation of our upcoming fiber installation with the hope of good network performance throughout the home.  We have been continually frustrated that our chromecasts over wifi simply do not work on this system.  The ONLY time they work is when casting from a PC, or after factory resets and the setup wizard on the chromecast every time we attempt to cast to them.  They continually disconnect from the network when using a mobile device... android or IOS over wifi.  I am attempting some of the settings I see recommended in this forum (kudos to you all!).  However, it would be great if the Netgear forum  moderators would take the abundant evidence in these forums and get it to Netgear Dev to correct the issue in an upcoming patch.  It should not require all of us calling in spending troubleshooting time with customer service trying to resolve this when it is clearly a known and widespread issue.  My generally new chromecasts should work with my brand new MR60 mesh wifi.  Ensuring that systems work with common devices is a minimum viable product requirement it would seem.
