TimeFinder Premium Subscription Not Syncing Across Devices

I just purchased a one-year subscription to TimeFinder Premium on my Android device.

on my android is working fine.

However, the premium features aren't showing up on my iPad, even though I'm using the same account. When I click 'Restore Purchase,' it says there's no purchase to restore.

i did just send picture of the problem to the e-mail support@timefinder.app
