Issue with activating cross-save to Xbox account

[Azqos]

I have an old warframe account from back on ps4. I have managed to link cross-save to a pc account and have them both linked to my original ps4 account, but when I try to link it to my Xbox account to be able to play on my Xbox, instead of coming up with a sign in option it immediately goes back to the home page and claims I’m already signed in. I have signed into the website via the pc account, so I am not sure how I am already signed in, and my Xbox account is not linked as it’s only showing PlayStation and pc. Does anyone have any tips or tricks to get around this as I haven’t played for a few years now and was really looking to get back into warframe. Thanks in advance! :)
