Copy to Call Cycle and Apply Call Cycle on My Schedule Agenda View are not available in CRM for iPad.
Currently, this is working as designed.
Copy to Call Cycle and Apply Call Cycle are enabled only on the Week view.
In the Classic UI, the Agenda view only shows one week at a time (there is no infinite scroll), so it is clear to know which week is to be copied or applied.
With Sunrise, the Agenda view has an infinite scroll. If the user scrolls a few weeks, the system does not know which week to be copied or applied.
