Hi,
We are using AEM6.3 with SP2
1> Enable it the reference option in touch UI:-
In classic pages we can see the references of a page by clicking on sidekick .But in touch UI the option is not able on page level .It can see only on site.html
So How to enable it the reference option in touch UI at page level may be under "page information"
classic:-

Touch ui:-

2> References don't show up on touch UI under sites.html:-
Classic:-
When clicked on "show References" from side kick it shows the pages it has been referenced.

Touch UI:-
But the same page when tried for references using sites.html does not up any results.
Could some provide inputs as what could be the reason.

Thanks
