“Legitimate Interest” blocks all ads

Hello,

When users just “accept” the basic “Legitimate Interest” instead of “Accept all”, it seems to me that Adsense ads should still be displayed, even if they are not “personnalised ads” but simple “non-targeted ads”. Am I right ?
Well I’m guessing that because I tried on different websites that are using Quancast.
But on mine, when I just accept “legitimate interest” ads don’t load.
In other words, only the “accept all” works to display ads.

Is there something I did wrong when I implemented Quancast? Is there a way to trigger the loading of the “standard ads” by adding some code in the Adsense snippet?

Thank you for you help
