Hi @Olivier Fischer! 

Nancy from Customer Support is here for a moment. 

We've received reports from 3 different users about the described issue lately so the team is operating under the theory that it is possibly a bug. However, so far the investigation and testing on our end failed to reproduce the issue to make sure it's present.
 

Our Technical Engineers are already in touch with you and will do their best to help you get things back to normal. 

Hello,

I am in contact with support, too due to the fact that I have an enterprise plan.

But it is good that we are not alone to have such problem

Olivier
