Hi Elakkiya,
To clarify the working of the app.
It's built with multiple ContenView's (User Controls), so the MainPage has a ContentView element, that is swiped/replaced with the menu/UC selected by the user. Currently there are 30+ UC in the app and it works perfectly on mobile devices.
So your suspicion is partially
true, as the UC containing the SfAccordion is not loaded as first, but the SfAccordion is defined in the proper UC.
I hope, I described understandably the workings of the app.
Regards,
Attila
