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"
2> References don't show up on touch UI under sites.html:-
When clicked on "show References" from side kick it shows the pages it has been referenced.
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.
Without going too deep here, there were some issues in 6.3 where some ACL's got overridden (NPR-23208) and the reference-adjustment-service user didn't have jcr:read on /content.
It's mentioned in the release notes
NOTE -- AEM 6.3 is end-of-core-support in April. It's time to upgrade.
