Hello Vignesh,
Thank you for your quick and detailed reply!
I am using the same latest chrome version and my grid code is almost exactly the same.
However now I realized what the difference was.
In my code I had enabled AllowReordering="true" for the SFGrid component
For some reason, when this is enabled, the sorting in mobile view no longer works.
Personally for me the solution is simply just to remove the AllowReordering="true" since I no longer need it.
However I'm curious if you can experience the same thing if you add AllowReordering="true" in your code.
It seems a conflict between "sorting" and "reordering" operations while in mobile view.
Thanks,
Sorin
