Who notice about "cart" in Store in 18282 ? It's weird, because it is the same version like in 17763 and in 17763 there is no cart in Store (At least in my Store).
There seems to be a bug in the account manager. Settings > Accounts > Email & accounts > Add an account. Attempting to add a google account results in the Connecting to a service dialog no accepting mouse input.
I think that cart has been there for quite sometime now if I could remember properly. However, it a store to say the least.
The color used in the 18282 Windows Light Theme is 200 230 240 #C8E6F1 If you try this color in 1809 you get this This Color is not Supported
