Last week after updating to the new launcher I was not able to go to the realms menu anymore.
to launcher saying invalid session Id and propose me to rerun MineCraft.

After testing my two account and redoing the update from scrach I am still not able to get acces to my realms environement.

Cheking some of my friend they actualy can go to my realms servers and play normaly even after the update.

I hope something can be done about it.

Bernard
