Duo subscription about to expire for second account

I updated my subscription from a single user to a duo for my daughter. I download the app on her phone it was not easy to try and set up her duo. It first made her an account to be charged on, so I cancelled that one. Then I sent her the link that says I am paying for her subscription. I checked her account and it says it had expired in January of 2024, but does not say anything about expiring in within 30 days. Eventually I think I connected her to my account but then I got an email that said her account is about to expire 6/17/26 and that she would have to pay $14.99, but I already paid for her account. Why will she be getting charged if I already connected her account with mine. I see her name on my account, it says I have duo and I can go back from switching accounts. Why is this so difficult?? I changed from Spotify to here because of all of their politics, but they made things easy. I have had so many issues since opening this app. Can you just make things a bit easier?? I feel like I send one of these every month due to errors. Can someone help me make sure I am not going to get charged for two separate accounts when I am already paying for it?? Thank you!!
