Since around 15 February there is a Huge drop of traffic for Safari and Microsoft Browsers on Mobile Device Type: "other" (Desktop) on domains that have s.cookieDomainPeriods: 3.

It also happened with Google - Chrome - but from around fisrt April, Chrome traffic is slowly resuming back to normal.

Is there some Safari and Microsoft update that Adobe should be considering? What could be the reason this is happening?

Thanks
