Malicious Website

It seems that Office 365 in some countries identifies Glide as a malicious. I had this feedback from Germany and France. Does anyone get this

Problem occurs when trying to install an app. Few weeks ago we had a similar issue in France. It seems to have disappeared…

So far it seems to occur only in Europe. Here is the same thing from France

It happened with my client in Indonesia.

Do we have any idea why this is occurring? Can it be either due to a new or old update of MS?
