Attending online bhartanatyam classes at home

Hi, I am a mother of a teanage girl 16 year old and I was taking her to classical dance classes from past 10 years .Recently during pandemic as everything became online , even our dance classes were being conducted online and so my daughter is attending her classes weekly twice or trice from our own flat . As any other dance form this involves taping the feet on the floor due to which some noise happens to the flat residents just below our flat. Other than this neighter we are using any loud music nor gugroo . The flat owners below us complained to the society and the society permitted saying its max three hours weekly and that too after office hours. But the flat owners are rigid and saying its effecting their jobs since they are also working from home and that too in different time zones. They were asking us to stop the activity and saying how come big girls do such activities while we share common floor . ( they meant Our floor is their roof). They even went to police to file a nuisance compliant on us. Please advice.
