Unable to connect to Azure Log Analytics due to Insufficient Access error

I am unable to connect Grafana to Azure Log Analytics. I’ve tried with a local install of Grafana and one in my Azure subscription (I’m using an MSDN subscription to test Grafana). I can connect to Azure Monitor successfully, but using the same Service Principal or a different one, I cannot connect to Log Analytics. I have followed the guidance for setting up the Service Principal and done it multiple times, with no success
Error is

  1. Azure Log Analytics: Forbidden: InsufficientAccessError. The provided credentials have insufficient access to perform the requested operation
    What am I missing here?

So it appears to be an issue with the current version of Grafana. I tested the version 6 beta and it worked no problem using the same Service Principal set up previously!
