Marketplace Error -3

Was about to post same but under private listing because I belive the ID Number to be a unique Identifier, please inform on what to do if we get this issue as there is nothing in any of the minecraft support pages regarding this error.

Same here however it only happens on Windows 10 not on iPad or Switch so its a Windows 10 issue. Also the link they give you if for Java support???

But try downloading update Windows 10 1909 and see if that helps

This is also happening to me currently and ive done everything i can to try and resolve the issue from my computer. Meaning if my computer made the issue but nothing i tried worked

I'm having the same issue on Windows 10. Installing the Windows 1909 update didn't work for me.

This issue has been resolved for me.

How do I fix this for my daughters tablet, not PC? 

I have this issue and i can't join any realms and server because i can't use the marketplace. I don't have any issues with my internet.
