Hi there,
i cannot see the issues on screen.
What i can see is your site is making around 600 network requests – 90% of which are adverts.
When google performs the mobile friendly test it fixes its server resources to a reasonable number. If your site exceeds this allocation then it sometimes fails to load CSS and JS files needed for it to display correctly. And you get these ‘false’ errors.
So optimizing your site is the best fix. I would normally suggest these tips: here:https://generatepress.com/fastest-wordpress-theme/
But with the amount of advert requests i am not sure if will be of much benefit.
