I think I was charged twice

Start with the list rather than the feeling, because a pending authorisation often looks like a second charge on a bank statement and disappears on its own.

Open your plan page (the Fitiva plan row in Settings, or the same row in your profile) and the billing button there opens the Stripe portal. Every charge on your account is listed there with its date and amount. A coach also has Financials for money athletes paid them, which is a different list.

If the portal really shows two identical charges, tell us with the date and the amount and we will look at it. Ava can open that ticket for you if you ask her to, and she will tell you what she wrote.

One thing Ava cannot do, deliberately: she cannot refund, cancel a charge or promise that one is coming. She can raise it and tell you what happens next.
