Heiya,
on the talk page of the ContactPage extension [0] it was reported [1] that adding a link to the contact page in the footer section of the skin [2] does not work when using the MobileFrontend extension [3], i.e. the mobile view. I just shows up for the regular desktop view.
It was suggested that we should try asking for help on this mailing list. Since I am not a programmer ...
Help will be appreciated and the solution will be added to the documentation page of the ContactPage extension as soon as it is known.
Cheers Karsten
