Hi there,
Thank you for reaching out to us.
With regard to your concern, you may set the frequency limit on account level. You may want to check this
guide for your reference. Once the frequency limit (depending on your configuration) has been reached, the Ad Request will return a No Fill Error. In your use case, the user will no longer have a chance to tap the button to see the ad as there is no loaded ad at the first place (given that the user has reach their frequency capping limit).
Regards,
