How to use tailscale remote desktop with Private Internet Access VPN?

Hi guys,

I have tailscale enabled on a PC which I remote into. I also want to have a vpn running. PIA VPN offers split tunnelling so I can enter ip addresses or desktop applications that I can select to not use the VPN. I have added tailscale to this after following this guide. However I still cannot remote desktop into the PC.

Can anyone assist?
