Xbox Apps for iPadOS giving sign in error.

Howdy.

Unfortunately, it appears that the Xbox app now requires at least iOS (iPadOS) 12. Just checked on an iPad 4 and got the same result as you.

I signed out on Microsoft Store App, and then signed back in using the same Microsoft account, but I cannot sign in on Xbox App it says, "We couldn't sign you in to Xbox live " and gives this error number: 0x8015DC0B.

No VPN, direct connection through home Wi-Fi. iPad 8th gen, fully updated. I deleted and reinstalled app prior to posting. The issue is that the log on page isn’t correctly encoded to allow clicking the “log in” button. The same issue exists in the Xbox Live iPad app.

I tried to replicate your problem in my iPad.
But I was able to sign in without problems

Let’s try to isolate the problem a bit more:

A. Go to settings > general > transfer or reset iPad > reset > reset network settings
Once the iPad restarts give it a new try

B. Go to settings > safari > clear history and website data
Once you select that
Go here in safari https://account.microsoft.com/profile and sign in with the desired account (select keep me signed in or something like remember this device)
Do the same on Xbox.com
After that reinstall Minecraft and try again

I followed your instructions. Login from the app is still not working. From the website, the reply is “We can’t sign you in. JavaScript is required to sign in. Your browser either does not support JavaScript or it is being blocked.” The same thing happens on Xbox.com.
