Hi Renee,
Sorry about that. Please don’t purchase Pro again. Open the Pro version screen in WorkingHours and try “Restore purchases” while signed in to the store account that holds the subscription. What message do you get?
Please also tell me whether you’re using iOS or Android, your WorkingHours and OS versions, and your device model. These details are listed in Please read before posting and will help me investigate why the active subscription isn’t being recognized.
