We recently upgraded to AEM 6.5 version. The problem we encountered with that is our custom emulator, which we made by overlaying "/etc/mobile/groups/responsive" inside the /etc folder itself is not working in 6.5 version.
I tried multiple things like overlaying the OOTB emulator under /apps/company/components/. But that also does not work.
Does anyone have some idea why that is not working? Please help.
I was able to figure it out. So, it seems that the path to emulator is changed from /etc/mobile/groups/* to /libs/settings/mobile/groups/* in 6.5. To make it work, I just copied the /mobile node to /apps/settings/ and referred that path to cq:deviceGroups property in my page template.
