Your IT has set up Conditional Access policies with a Sign-in Frequency set too low (it should really be labeled as a period, because it defines the time period that will occur before reauthentication is required). For regular users like all of you, forcing reauthentication that many times each day is excessive and just cruel on the users. They maybe thought it would make them super secure, but it only trains the users that MFA is an annoyance rather than an important security feature.
It’s a setting that can easily be changed, so make some noise and see if you can get some feedback passed through your org structure to IT.
I don’t think I’ve ever had to sign into Teams (PR Outlook, for that matter) in my desktop. Mobile, I have to after changing my password. I assumed all the MS apps signed me in with my domain login on my laptop. On weird issue I have is things like SharePoint and Dynamics 365 asking me to sign in again after its already brought up the site, and clicking the button to do it just brings a blank pop-up that immediately disappears and I’m logged “for real” I guess.
