Providing Early Feedback - Simplified Teams app bar 557169

How do we provide early feedback to prevent this from happening or requesting the option to disable this feature? If anything, I want Teams to de-simplify. Microsoft keeps going out of their way to hide things that are crititical to productivity.

I mean - generally - how do we get Microsoft to stop making things worse? It seems like the recommendation is to use the feedback button in the app; but by that time it's too late. Telling the 100+ people who ask me what Microsoft broke this week to use the feedback button is not helping avoid their distaste and distrust of this platform. This is why people are avoiding Teams and prefer text messaging and WhatsApp. We desperately need to increase adoption but Microsoft keeps obscuring features that lead to increased confusion.  

Where do we make requests to decrease simplicity and increase productivity?
