Number of ads viewed not updtating

Description of the issue:
The number of ads viewed in settings does not reflect the true number of ads sent to my phone.
I recieve push notification adverts, perhaps 1 in 10 of these actually appear in my number of ads.
Even if I view/click the ads (which I supposedly do not have to do) I get a low success rate with views that are actually counted - perhaps 1 in 5, but better than just receiving the push notifications.

Expected result:
An accurate count of the ads viewed.
