At first it told me YOU MUST LOG INTO WARFRAME ON YOUR NINTENDO SWITCH ACCOUNT BEFORE YOU'RE ELIGIBLE FOR LINK/MERGE.
Unsure of what they meant (logging in on website or the game itself) I tried both, played for about an hour on switch, then tried logging in on the website and it gave me this:
YOUR WARFRAME ACCOUNT MAY NOT BE AUTHORIZED ON YOUR NINTENDO SWITCH CONSOLE. YOU MUST FOLLOW THESE STEPS TO AUTHORIZE YOUR ACCOUNT:
1) LOG INTO WARFRAME ON YOUR SWITCH
2) OPEN THE MENU BY PRESSING THE + BUTTON
3) SELECT 'PROFILE'
4) SELECT 'WEB AUTHENTICATION'
I'm still not allowed to link them in any way, and the web authentication button has been deleted so it just sends me to a dead end.
