Mobile view seems to be all over the place

I am using Sydney theme and it’s beautiful, but the mobile view seems to be all over the place. Colours are not the same on the menu, etc. The site title is displaying on some pages and “powered by wordpress” shows up even though it doesn’t on the computer. Do I need to do something special for the theme to be fully responsive? Any help would be great.
thank you

A link to your site would be helpful to see what’s wrong. Obviously, this is not the default behavior.

Okay here it is //edited as requested

I would appreciate you deleting the link afterwards, thanks

I think I figured it out! I have the Jetpack plugin and one of the features ticked off was “mobile theme”. I just unchecked it and the mobile seems to be better now. :slight_smile:
