Beware: immediate after upload into Stream, video is available in only 1 quality / rendition

A business user recent approached me with question why his uploaded video was only available in one, and not the highest bitrate / quality in Microsoft Stream. However, when we opened the video to inspect, he was pleasant surprised that all of a sudden the video could be played in more qualities, including with higher bitrates. This behavior is completely explainable, as on Stream side processing takes place to convert the uploaded video in multiple bitrates; and that processing simples takes its time to complete. But it is good to be aware of, and realize that you just need to be a bit patient for the different video qualities to become available.

Beware: Open Project Online resource in 'Edit Resource' blocks the automated modification of that item

The Project Online ResourcePool can be automated managed, e.g. to update a (Custom)Field of an EnterpriseResource. Something that I became aware of is that the automated modification is blocked in case the resource is opened in 'Edit Resource' of the Project Online Web Application (PWA). Apparent PWA applies defensive locking, and already immediate locks the resource through checkout when opening it in the form, and not delayed / just-in-time at the moment of possible save. The automation is blocked both when doing the modification via ProjectServer REST service, as when via the ProjectServer.Client CSOM library.

Open a PO resource in the ‘Edit Form’

(<pwa-url>/_layouts/15/PWA/Admin/AddModifyUser.aspx )

Automation code-snippet to modify EnterpriseResource via REST service

 $body = "{ 'Name':'Test Name', 'Group':'Test Group' }";
 Patch-ReSTRequest $pwaUrl "ProjectServer/EnterpriseResources('$resourceId')" $body

Combination of 'Edit form' + automation execution results in error
