@homerpez Posted below in another topic per ads. It is the end of the month and I always notice a slow down in ads. Usually, I still get a few notifications, but NTP and inline ads just stop or show up less frequently. This is my experience and it may be happening to you too.
You may have reached a cap for your region or for the ad campaign. The topic below has some information that might help explain. Also, posted the link to the ad catalog viewer. You can check if ads are still available for your region and if you are eligible to receive them.
