I just launched Pichon and let it upgrade - when it relaunched it was no longer signed in, and when I try to log in a just get a 
emoji. My credentials allow me to log into the website fine, and I also have the Mac app signed in with no problems. Worked previous to the upgrade, I don’t have any internet connectivity issues.
I’m sorry for this issue!
We are already investigating what might cause it. I will keep you posted as we go.
