I often have the message there is no add available see image - hence the purchase of medals- Ive also noticed that in general the system seems to have (only) a handfull of adds it that are rotating ( all seem to be mobile gaming adds) are there filters that are set too strict on the selection of adds on your or my end, my region is belgium/europe
Honestly I have no idea what google ads are providing in terms of ads, I myself can’t have them on (did this mistake once and they banned me for 1++ months) so been very careful.
The only filter I’ve placed is to avoid those casino and erotic stuffs.
your location SHOULD also be better than mine, some “developing” country. But from what I read, USA would be marked better.
