Have you tried on the most recent beta? I think it works over there, but requires some tweaks to the network monitor code in WireGuard. I had a patch somewhere here but haven’t spent much time testing it:

https://git.zx2c4.com/wireguard-apple/commit/?h=am/enable-include-all-networks&id=b244febfdf3069dd4e8db2d31f0368d5474d7616

Waiting for the final release of iOS 15.
