A single wg interface/config on your phone, with two peers, one for home wg and one for remote vpn, with AllowedIPs on the home peer as 10.10.0.0/24 and AllowedIPs on the remote vpn peer as 0.0.0.0/24?
Have you tried excluding the cidr of your home wg from the AllowedIPs of the remote vpn? Like not having 0.0.0.0/24, but one or more entries that end up excluding local cidrs.
The external VPN provider dictates what my interface's IP range is. I generated a new WG config using the UI, and it comes with interface IP 10.66.123.123/32. If I want my home ip to be 10.10.0.2/32, then I'll have to set it as 10.0.0.0/8, and the VPN provider didn't seem to agree with that.
I have two wg interfaces and I manually switch between them.
