IPv6 and Android Google play store updates on a Samsung.

[NetworkNitwit]

Not long configured my first proxmox opnsense firewall router(newbie). Using v25.7.x and its been working well. Last night I noticed my Samsung phone had 20 odd apps that needed to updated ,bit surprised ,so I tried & they all kept failing with pending...timeout.

After a lot of wailing and gnashing of teeth I gave the samsung a static IPv4 with DNS 8.8.8.8 and updates started to work.
So google told me its a IPV6 issue and I turned it off on the interaces and put the samsung back on DHCP and yes it works.
Now I dont really know why but I would like IPV6 working maybe its the future!

I'm using .internal as my domain is this ok & how can I see where its falling down when I try to update apps? I looked in firewall logs and couldn't see an issue, during the process I turned off my firewall & IPS completely.

I'm using DNSmasq and Unbound as OPNsense documentation suggests for default install 2026. Any pointers to other logs which could highlight a DNS/DHCP issue I would be appreciative.
