We are in the process of rapidly fixing all issues that we got after upgrading of our Studio UI and constantly shipping new versions (up to 30 releases per day).
Some updates require service reboot (backend) or changes to existing UI modules. Sometimes users can see networks errors of interface freeze. If you face such issues - please try your action again or refresh your page in your browser.
Once all major issues will be fixed (we need a couple more days) we will go back to our regular release schedule (2-4 releases per week).
Deployed applications are not affected.
We are sorry for the inconvenience we made.
