In-app ad removal

Hello guys
I’m preparing an application ad removal button
Question ;

  1. How can I turn off ads for a certain period of time after watching the rewarded ad ?
  2. Do you think I should turn off ads in exchange for rewarded ads or should I use in-app purchases?

you can do it like -
when rewarded ad completes,

  1. disable all ads
  2. in a variable store the time of completion + minutes for which you want to disable ads.

then compare the current time with the time stored in variable at frequent intervals,
if current time value is equal or greater than value stored in variable, then enable all ads again.

You can use API based time to be more safe from easy device time manipulation.
