MS Teams window not hiding

Hi!

I am experiencing this weird thing that happens to my Teams app. Picture this, I have my MS Teams window on full screen and I am in a meeting, but I want to switch to chrome quickly, so I normally would go to the taskbar (Windows 10) and click the chrome icon. But the teams window still stays on top of the all other apps, which is really annoying, as I have to minimise teams each time I want to switch apps! Is there a way to fix this?

Many thanks and best wishes, 

Oliver
