new XR500 chromecast built in set up

[erfont]

I just upgraded to a XR500 from a 6300V2 and I can not get chromcast built-in set up on either of my Nvidia shield TVs. It worked without any issue yesterday with the 6300v2. I'vebeen trying every possible solution/config i could find on this board but nothing works. Anyone have any ideas?

   "can not" is not a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   Think, for a moment, about how little useful information that
non-description conveys to the non-psychics in your audience.

   See "not a useful problem description [...]", above.

things i've tried:

-turned off smart connect and set up all device on the same 5g wifi

-checked and updated firmware on all devices: phone, both shields, router

-deleted stored wifi networks. reconnect and save only the 5g. all device show connected to it in DUMAOS

-deleted all devices from Google Home. 

-factory reset one of the shields

-toggled UPnP

-toggled IPv6

Everything was working fine yesterday with the R6300V2. The XR500 is the variable

Could you try using the 2.4GHz network instead of 5GHz please? I realize you'll want to use 5GHz for high bandwidth so just for trouble shooting purposes.
