Grid Legends won't connect to your servers on console "X Box"

I'm super *issed off,  all of a sudden, I've lost quite a lot of game save in Grid legends !! nearly all the caree and objectives are reset to the beginning again, the same goes for my sons account as well !!! And the thing is, the one time there's more data, the other time I try to restart the game, there's more or even less, WTF ?!!🤬
