Default page showing on mobile devices

Hi, I have successfully installed WordPress multisite network and created subsite. When I visit my subsite URL i.e https://mydomain.com/site1 then it shows perfect on desktop view. Homepage is showing correct on desktop devices, but when I open same URL on mobile view , home page is not showing, I can see default page on mobile view. Is there anything wrong with my theme setting? How to set homepage for mobile view?
More info: my current installed theme is : Enfold .
please help.
