You paid for Pro or Familia, but the app still shows you as Free. Do not pay again: what is missing is for the app to recognize the purchase you already made. The app has no button to restore purchases. Your plan is tied to your facturillo account, and the app reads it again when you sign in, when you open the app and every time you open the plans screen.
First things first
Do not pay again. You already paid: the app only has to read your purchase. If the steps below do not do it, contact us and we will look into it with you.
How to get the app to recognize your purchase
Sign in with the same facturillo account you paid with. The purchase follows your facturillo account, not a phone, so in a different account you will not see your plan.
Fully close the app and open it again, with an internet connection. When it opens, the app identifies your account and loads your plan.
Open the plans screen. From your personal account, tap your photo at the top right of Home. In your profile, under ACCOUNT, tap the Subscriptions row (the banner with the logo). Every time this screen opens it asks for your purchase data again, and it updates by itself when your plan changes. Wait a few seconds with it open.
Look at the bottom button, on the tab of the plan you paid for (PRO or FAMILY, in the selector at the top). If the app already recognizes your purchase, instead of Subscribe it says Manage subscription, with the date it renews. If you paid in the other store (for example on Android and you now open the app on an iPhone), it says Manage in App Store or Manage in Google Play, and that also means your purchase was recognized. These labels also mean the app sees your purchase: Reactivate with the plan tag (you cancelled the renewal, but the plan stays active until the end of the paid period), Update payment method (the store has a problem with your payment), Upgrade to Family on the FAMILY tab (you have an active Pro) or Switch to Pro on the PRO tab (you have Familia). If it says Back to with the plan tag, the app sees a subscription that already ended and needs renewing.
If you are still on Free, contact us. From Home, tap your photo at the top right, scroll down to SETTINGS, tap Support and then Support requests. Tell us which store you paid in (App Store or Google Play) and the date of the charge. The full walkthrough is in Priority support and how to reach us.
If you bought Familia
If the plan is Familia and the shared account shows read-only mode, see My family account went read-only. Once the subscription is renewed, the account returns to normal and no one loses their receipts.
