We can hide the Time slot using TimeScaleproperty for which the default value will be true. When the property value is set to false then default time slot will be hidden within the Schedule and for the same we have prepared the below sample. Kindly refer the below code example used in the sample.
Kindly try the above sample and if the issue persists, try to reproduce the error in a sample and revert it back to us. Or else you can share an image/video demo/code example/sample (if possible) to proceed further.
