Upnp problem

[AdamN]

I've created a test build with UPnP Timeout setting for iOS here https://sam.nl.tab.digital/s/HAfDeoYsYTjx4CR
Please try it with UPnP Timeout = 5000 and see whether your iPhone 12 pro can detects your router/UPnP device or not.

If it can detects UPnP device using a high value such as 5000, try lowering the value by 1000 or 500 until it reached 2500, and let us know what is the smallest value that works, so we can use it as the default value on the official version of PPSSPP later.
