I have a very simple home network setup

ISP —— ISP Router with integrated wifi (Device B) —— Google wifi (main) and 3 connected mesh pods

✅ Amazon.com works on mobile hotspot on my laptop
✅ Amazon shopping app works on 5G

✅ Amazon.com works on SSID of Device B on my laptop
✅ Amazon shopping app works on Device B

🚫Amazon.com not working via Google WiFi SSID
🚫 Amazon shopping app not working via Google WiFi SSID

Troubleshooting done so far:
- Disabled Preferred Activity
- Changed DNS from ISP to Google, Cloudflare, NextDNS, OpenDNS
- Disabled IPv6
- Disabled guest WiFi
- Changed LAN subnet pool
- Disabled Family WiFi setup
- Did factory reset

I know some of these steps have no relation to the issue but tried. Looking for ideas on how to resolve.
