Cannot purchase from Minecraft store and ALL achievement are not unlocking

I am having 2 issue in Minecraft Windows 10 edition.

I cannot purchase anything in the minecraft store because it cannot connect to the Minecraft store. It pop up a error box whenever i try to do so.

I also cannot unlock any achievement in Window 10 edition. I am in survival mode and every new map i created, EVERY achievement doesnt unlock. i am using default behavior and resource pack.
Achievements in pocket edition and Advancement in Java edition work fine.
