MS Edge chromium on start connect to pages without proxy

Hello,

we are trying to deploy MS EDGE chromium in our env. We are now facing issues, that on start Edge ask for proxy credentials. After some investigation i found out that EDGE is openning some web pages probably not with user credentials. for example: config.edge.skype.com, nav.smartscreen.microsoft.com, ntp.msn.com, etc. So the result is, that users recieve authenticatio prompt. After they cancel, the browser works properly. But this is how it should not work, it degrades users experience. Any solution for this ? 

Thanks
