Connection issues with Google Fi

Using a Nexus 6P on Google Fi, I'm noticing that when roaming between cellular and WiFi, I occasionally lose the ability to use WireGuard. Coming from Verizon, I didn't previously have this issue.

I can only assume this has something to do with Fi manipulating the routing table in such a way that breaks WireGuard connectivity. I verified that WiFi Assitant is disabled. A simple tunnel-up, tunnel-down doesn't seem to fix the issue. Rebooting fixes the issue.

Next time the issue occurs, I can dump the ip rule list, but may need some assistance figuring out which ip tables to pull. Is this the info that will be needed to troubleshoot?
