I can confirm that is is still happening. Teams app is still not honoring the flag set. Disabling the welcome message via group and then adding Team members through Teams UI still results in a welcome message being received by the new member. If the member is added through powershell or azure-ad there is no welcome message sent.
This feature is still in the planning stage. No new updates are available at this time.
Sorry for the delay on an update on this one! I’m hunting down the status for you and will update once I have it.
Also, if you are interested in participating in testing or surveys for this, just tweet me at @skprufo.
