Google Ads making image posts disappear on Mobile

Hi there,

Thanks again for the awesome theme!

I modified the functions.php to change the thumbnail sizes:
// Thumbnail sizes
add_image_size( ‘thumb-small’, 160, 160, true );
add_image_size( ‘thumb-medium’, 520, 0, false);
add_image_size( ‘thumb-large’, 720, 340, true );

That said, when I add my Google ads, when I scroll on my mobile phone, the image posts disappear and reappear.

Is there a fix for this problem?

Thanks
