Please optimize the game FFS

Remove the Microsoft Log In! When I log in, it takes minutes just to load anything. There's always errors and my skins take forever to load. And if I don't wait for them to load, I have to manually go back and reselect all my skins ingame. And making a skin and loading errything in it, takes so long. And also almost everything in the game has the Purple/Black missing texture. 

Literally all the things you buy (Skins, Textures, and Data Packs)  REQUIRES an internet connection and to log into the MS account to have access to.

 Why can't we just link our Nintendo Accounts with the MS accounts? And EVERYTHING we buy is downloaded onto the Device so we can access it On and Off-line and without having to "Log In" or deal with logging in.

Then! Optimise the Market. Reduce these ridiculous load times. And fix the random Frame Rate drops in game. Almost every other fcn minute of playing with my friend, my frame rate drops to less than 10fps randomly for no reason. FIX THAT ALREADY!
