I’ve seen general discussion re: this elsewhere and looking for help and input.

When 2 devices are on the same WiFi network, they are sharing web-site tracking data. How is this occurring and how can it be blocked?
Here are the details:
device 1
Does not use instagram
Most activity is web sites, YouTube and amazon
device 2
app: Instagram
Behavior: Instagram shows ads based on activity from device 1
Network
All devices behind firewall with NAT

how can this be prevented or blocked? Any thoughts on how this is done?

Thank you!
