NFS:HPR crossplay & friend issues

Hi all, 

I'm hoping someone can help here as I'm really at the end of my patience. 

I own NFS Hot Pursuit Remastered on PC - through Origin. My brother also own NFS:HPR but on Switch. Even though this game has cross play advertised all over the internet I can't see him and he can't see me, there's just nothing there at both ends. 

He has his own Origin account through the Switch and can log into the web based verison on his mobile and I use the Origin app on my PC. It took us nearly 2 hours to add each other onto our friends lists and only we only managed to do this when he signed into Origin on my PC - as on his web verison my friend request just wasn't there. 

So now that we finally are on each other's lists we want to play together but like I said, there's nothing showing anywhere. He's actually playing on Switch as I type this but according to my Origin account and in-game in NFS he's offline.

What kind of broken mess is this? Does anyone have any ideas how this can be sorted so we can to play with each other as the game blatantly advertises?

Thanks in advance
