Yep, I just put in for a refund also. I thought I'd be smart and order through the Microsoft Store. Big mistake! After paying for the product, I went to download it and it said it couldn't find the device to download it to. Duh! After an hour, I gave up and requested a refunt.
I should have checked Amazon first. The reviews of the sim are absolutely horrible. Note: Just rechecked Amazon and they have pulled the 2020 off the page! People must be going crazy with this.
Assuming I get my money back from the direct purchase attempt, I'll try again in a month. Working with Microsoft and Windows has always been a nightmare, and I hoped that has changed since I left them years ago. Guess I was wrong...
