@elisabettai together with @YuryHrytsuk we found out that this is currently broken on production and should have highest priority since there is no feedback for the users

@GitHK, I am a bit confused here. Where did you see the problem?
On s4l-lite, I tried to open 2 projects at the same time and I got the expected error message

On the other production deployments, users are free to open as many projects as they want.

@elisabettai this is on TIP prod
