Do not see solutions after missions solving

Today I have faced with the problem. The problem is that there is no block with solutions after I have solved a mission + there are no buttons to share a sulution. It is for any mission i am trying to solve today, before today it was fine. I am using Chrome browser. Restarted my PC and log-out\log-in from the site two times.

P.S. In Edge it still working fine.
