Hey there!
I am using Ezoic ads and I’ve selected the responsive ad units (doubled checked again) The problem is that the ads fill more than the main content width on the mobile version while the desktop one is fine. It creates a horizontal scrolling on my page.
Please check this: https://prnt.sc/uckMCs-UwJq9
I am only facing this problem on Generatepress and the rest of my themes are working fine with all those same ad units.
Although, if you visit the page probably will not see the ads because Ezoic shows different ad sizes depending on each time.
Thanks
