Any updates to this original bug report? Mine (Bug # FB9329234) was resolved stating - working as designed.

I have the same behavior while using on Device VPN (NEPacketTunnelProvider). No User Agents (at least 95% of the times). Randomly, I see few user Agents reported on some traffic. We have a webpage that renders different functionality / content based on the operating system. We user UserAgent to match for OS @eskimo

I have same observation with BETA 2 or Public beta. The userAgents appear in random case. The results are not consistent. It seems more like a defect in iOS 15. Also, the behavior is same with or without iCloud Private Relay ON/OFF.

Hi, Did you manage to solve this? It does not help even if we bypass the traffic from these apps going via tunnel. Some apps like pokemon go detects vpn/proxy based on traffic, and hence we were able to solve this by bypassing the traffic. But Hotstar or SpectrumTV does not work, until VPN is turned off. Is there a way to handle this using the Packet Tunnel Provider?

@yashipallav - did you solve the hotstar app detecting VPN issue? How did you over come this issue? @eskimo - I have a similar problem with Hotstar, Spectrum TV apps detecting VPN (not through traffic) by some means. I have bypassed all traffic from these apps to going through tunnel, but still these apps won't work.

Hi did you manage to solve this problem? I have similar issues

Hello Eskimo, I see your response - "No. If a device has both Wi-Fi and WWAN, services are expected to transition to WWAN when Wi-Fi is unavailable." I understand this is not possible, but this would mean every time the network switches the vpn might reconnect if the on-demand is on. Wouldn't that cause the VPN icon to appear more frequently? Is there a way to prevent the VPN icon not flashing every time the network changes? Note: I restart the tunnel every time a network changes (wifi-cell and vice versa) - Is this the right thing to do? Is the vpn icon flashing because of tunnel restart or it happens irrespectively?
