Hej,

I have noticed the dropp in organic traffic in August - about 20% (on mobile version of site - m.example.com). The desktop version of site haven't experienced the dropp.

I have noticed that in SERPs (desktop) when I am typing the relative path of URL, both versions show up. Could that be a signal that I can have a problem with duplicate content? Could it be that a mobile version is a duplicate to the original site?
