As for the current version of the Telerik Scheduler, if using the Adaptive Rendering Mode for the Scheduler
the Adaptive Slot Height feature (https://demos.telerik.com/kendo-ui/scheduler/adaptive-slot-height) does not work for a mobile screen in a Month view. Due to this, there is no opportunity to dynamically change the height of the slots in a Month view so that they can fit the events in the specific slot. Thus, in case dots standing for the events in a month view are customized and replaced by regular events, the scheduler cells do not change their height to account for the events number. The only options to display all the events per day in a month view on a small screen are now either to make the height of all scheduler cells really big (not user friendly) or decrease the height of the events depending on their number to fit them in a cell (not desirable behavior).
Taken all this into consideration, adaptive rendering mode needs the same adaptive slot height feature which exists now only for a regular mode of the scheduler.
