Lost connection to Dragon Mania Legends

After a restart today all of my progress in Dragon Mania Legends is back to the beginning. I have tried re-installing the game, signing out of the Xbox Companion console and another restart but nothing works. There was (what I assumed to be) a server id
in the top right corner of the launch page which has now changed to a different one.

I did read about issues with Xbox Networking and did try the Fix It option in settings. This fixed it for a while but it doesn't stay fixed for long.

Can anyone help please?
