Microsoft Teams Release Processes - Why do I not see a feature but my colleague does?

This was not all of the information I was looking for, but it is a start. While I understand that MS needs the time to roll out features, having some users have disparate experiences tends to degrade the user experience. For instance, the Teams Together Mode. One user can have it, and others, wanting to use it will not. That creates a disparate experience where if someone wants to kick off that new experience in their next meeting, because they're excited to share what they've learned, they don't have the feature. - Bad user experience and also creating issues with level 1 support seeking further clarification as to why they don't have that feature. 

What I would suggest Microsoft do is create talking points that would be available through their Microsoft adoption guides. It's important to note this and not just stumble upon this information. We need to be able to speak to it and temper the expectations of our own user base. I'll be able to take this information and craft it into a watered-down version for my company.
