Hi everyone, I just installed and this error appear, i can't sign in on PowerBI Microsoft.Data.Mashup.Preview.DownloadManifestResult+JsonRemoteExtensionInfoArray.Encountered unexpected character...
I've got the same issue with our PBIRS JAN23 deployment.
I can clear the issue once allowing the user to access the web.
Appears without internet access you get this error, with you don't.
All our users have to accept a user policy before they can access the internet so all get this error until they do so which is an absolute pain in terms of PBI Desktop rollout with rubbish comms explaining the error.
Any help with this would be greatly appreciated, haven't been able to provide our main 250+ users with the latest version since they introduced a call-home feature at launch May 2022.
