Windows 10: Can't login to Microsoft Store or Xbox Companion app

I had my account under and old email I made just for an Xbox 360 account way back when. Today I finally changed it on Microsoft's website updating it to my current email which is now the primary and only email on the account. I can login just fine on my Xbox one X, Microsoft's website and the Xbox website. Everything is working 100% normal. Everything is as it should but now with my actual email attached to the account as I wanted. However, when I try to login to the Microsoft Store or Xbox Companion app on my PC I am given these messages. "We encountered an error. Please try signing in again later." or "It doesn't look like you're connected to the internet. Check your connection and try again." That message also comes with error 0x800704cf. The first message has no error code.


I don't know what to do to get it to let me login to my accounts. I tried looking it up online but no one else seems to have posted this same problem that I can find. And in regards my internet connection my PC is in the middle of doing a dozen other things with an internet connection as the Microsoft Store is telling me I need one so clearly those error messages have no clue what they're talking about. All i'd like to do is login again so I can download and play Halo Wars 2 in anticipation of Halo Infinite.
