Wide Area Bonjour - Issues with Chromecasts

Hi All!

   I have Wide Area Bonjour application configured on DNAC and on one of my switches where all APs are connected. Bonjour service is configured for Chromecast service to work from different subnets. There is very strange problem that only a few people`s laptop can find connected Chromecasts as remaining ones either finds it after 10mins or don`t find it at all.

Above is switch configuration:

service-list mdns-sd LOCAL-AREA-SERVICES-POLICY-IN permit 1
 match message-type any
 match service-type _googlecast._tcp.local
!
service-list mdns-sd LOCAL-AREA-SERVICES-POLICY-IN permit 2
 match message-type any
 match service-type _ipp._tcp.local
!
service-list mdns-sd LOCAL-AREA-SERVICES-POLICY-IN permit 3
 match message-type any
 match service-type _ipps._tcp.local
!
service-list mdns-sd WIDE-AREA-SERVICES-POLICY-OUT permit 1
 match message-type any
 match service-type _googlecast._tcp.local
!
service-list mdns-sd WIDE-AREA-SERVICES-POLICY-OUT permit 2
 match message-type any
 match service-type _ipp._tcp.local
!
service-list mdns-sd WIDE-AREA-SERVICES-POLICY-OUT permit 3
 match message-type any
 match service-type _ipps._tcp.local
!
service-list mdns-sd LOCAL-AREA-SERVICES-POLICY-OUT permit 1
 match message-type any
 match service-type _googlecast._tcp.local
!
service-list mdns-sd LOCAL-AREA-SERVICES-POLICY-OUT permit 2
 match message-type any
 match service-type _ipp._tcp.local
!
service-list mdns-sd LOCAL-AREA-SERVICES-POLICY-OUT permit 3
 match message-type any
 match service-type _ipps._tcp.local
!
service-list mdns-sd AQ query
 service-type _googlecast._tcp.local
 service-type _ipp._tcp.local
 service-type _ipps._tcp.local
!
service-routing mdns-sd
 service-policy LOCAL-AREA-SERVICES-POLICY-IN IN
 service-policy LOCAL-AREA-SERVICES-POLICY-OUT OUT
 service-policy-query AQ 90
 ingress-client query-suppression enable
service-export mdns-sd controller DNAC-WIDE-AREA-BONJOUR
 controller-address X.X.X.X
 controller-port 9991
 controller-service-policy WIDE-AREA-SERVICES-POLICY-OUT OUT
 controller-source-interface Loopback0

   More info: in DNA center I see all connected Chromecasts as active Instances. But I also see a lot of Dropped queries. I tried to check debug logs but didn`t see anything with __googlecast._tcp.local logs and I think this dropped logs mostly for IPPS queries as I also configured IPP and IPPS but dont have any printer or other instance connected to DNAC.

 

I am struggling with this issue for a long period already and would be really thankful with any help.

BR, Thanks in advance!
