A large number of SCCM clients waiting for Matlab were stuck on waiting for content. This was due to server side rules blocking some file types. This has been resolved so clients can download and install Matlab.
Unfortunately, there appears to be a secondary issue where clients are not receiving policies which could kick start this install. We are continuing to look into this as a matter of urgency but in the mean time if Matlab is required for teaching we recomend logging on to run the advert from “run advertised programs” which will take about 20 minutes.
