Over a year old this post, but i'm having the same issue. I even rolled back the version thinking it was a update.
It's weird as if i add a route (system, config, routes) for an ip address to route out via the wireguard tunnel, start pinging it and then up and down the tunnel. I can see the ping go from 5-8ms (tunnel is down) to 20-35ms (tunnel is up) but i get the same DIFFERENT ADDRESS from device on the LAN.
followed the same guide as person above but also crossed checked with https://gist.github.com/morningreis/eeda36e8bb07dcb750d77e9a744776e8
*** Now working for me
I changed the 10.2.0.2/32 that Proton and the guide said to use, to 10.2.0.2/24 and it's all working now... strangely
