I am attempting to switch from Premium Family to Premium Duo and keep getting the error: "Unable to change plans. This could be because you're not eligible for this plan, you're already on it, or you don't have a stored payment method."
I believe I have a stored payment method; my Premium Family renews each month with a saved debit card. I don't see anywhere else to store one.
I have one other member in the family plan (so doesn't exceed 2 for Duo), but I even tried removing that member and still got the error.
I don't see anything else I can try. Why wouldn't I be eligible? Why is this failing?
I only see one similar post, but they're on Premium Individual and getting a different error:
