Can’t load into online.

Me and several of my friends have been trying to go into online and can’t since the update dropped. We’ve been trying for 4 hours and haven’t progressed at all. ( Were on Xbox one)
Whenever we join invite it will load for 2 minutes then say that there was a “Network error” then it says to contact the Forza Horizon 4 forum. We’ve tried restarting our Xbox, doing full shutdowns, trying different methods of inviting each other, joining invites from different hosts, and many other methods. We’ve also all restarted our internet’s and checking what the network status is.
At this point we’re all annoyed and would like if someone knew how to fix this.
