Teams on Mac - 365 subscription

Teams works well on iphone and ipad but its impossible to get going on a mac - I am logged in and it always told me to register for an account - BUT I HAD ONE - Urgh 

Then I saw that if you re register and call it a business account then it works - I did this and it works fine 

There has to be a bug in the home version that has been around for ages by the look of the boards.
