Sign-in and marketplace issues

I keep having to sign in to my Microsoft account via the whole "https://login.live.com/oauth20_remoteconnect.srf" thing every time the system goes into sleep mode, I turn off the game, or just go into the home menu for any reason. I'm tired of the constant re-signing in. Not only that but the syncing between the Switch and PC versions of Bedrock is messed up. It simply won't sync the worlds. Also, I keep having trouble connecting to the Marketplace, period. It sometimes won't connect at all, and when it does it takes a long while. Please fix this.
