New site, adsense, unusual stats

So I have several sites monetized with Adsense but such thing I haven't seen before.

Literally, my revenue from mobile users is 2500++% higher than my revenue from desktop users.

This is in the past 28 days.

38% are desktop…

I haven't seen anything like this before. I have 1 ad above the fold only on desktop. On mobile, I have enabled page level ads too.

Do you think I should place another ad above the fold, only on desktop, just after the </head> tag, 728×60? Maybe I should use some…
