Hummingbird Results for Mobile

I just recently installed and join WPMU Dev for our sites, and so far it is great! The question i have is regarding thr PageSpeed changes via Hummingbird for mobile. After enabling the changes, I have noticed a drastic impact on the Desktop PageSpeed Insights (as seen in both Hummingbird and via Google PageSpeed Insights).

What i noticed, however, is that the mobile PageSpeed Insights for the mobile version of the site is actually lower, with a score of 69 (score of 88 for desktop). I am just curious where to implement changes in Hummingbird to also affect the mobile performance as well.

Can you please respond to Anyone which you could help would be greatly appreciated. Thank you, and hope you have a great day.
