Serious sechole with pCloud Drive

If there is a computer which is used by multiple people and one of the users install pCloud and logs into pCloud then pCloud drive (p:) is created. This drive shows all of the users files in pCloud. The problem is that this drive is VISIBLE and FULLY ACCESSIBLE from all of the users in Windows if the pCloud user is not logging out but only clicks "Change user" in Windows. So all the private files of userA is accessible by userB even if userB doesn't even have pCloud app running! This is extremly problematic if you use pCloud on a Terminal Server for example. I didn't even find any warning about this in the app. The support told me this is a bug not a feature and that userA should use LOGOUT in Windows all the time and never "Change user".
