The activity issue finally just made me set to appear offline. I was irrationally paranoid that my manager or skip would see me away most of the time and think that I wasn't showing up for work, even though I was sitting there typing away.

The worst part is that even if I set my status in the status bar to "available" once I noticed it was away, it sometimes would just set itself back to away instantly. Opening up teams and clicking in the window seems to be the only way to get that to not happen.
