I'm trying to link my DVC account to my Disneyland account. After I input my username and pw, it says it's "All Set" but then when I go back into my profile, it's not showing. It asks, "Has your DVC account already been linked to another Disney account?". What does that mean? I linked it to WDW and DCL already. Why can't I link to all? It already makes us use the same pw for everything.
