My lifetime account is gone

Im unable to use my lifetime account and I dont know why.

Please! I buy it! And i deserves it

Hi @Lais_Flores, all past purchases are still valid.
The app doesn’t have accounts, but the purchase status is automatically recognized by the Play Store.
What type of purchase do you have - a subscription, in-app purchase, or Unlock stand-alone app?
Have you followed the guide from App is not unlocked although I have paid - Sleep as Android?
