Answer 1

I had the same issue,

There are a couple of reasons for this issue

1. Make sure you have included MatSortModule module in your App module

 import { MatSortModule, MatPaginatorModule, MatTableModule } from '@angular/material';

 @NgModule({
  imports: [MatSortModule, MatPaginatorModule, MatTableModule],
  exports: []
})

2. Make sure you have subscribed sort change in the ngAfterViewInit

  ngAfterViewInit() {
    this.sort.sortChange.subscribe(() => this.paginator.pageIndex = 0 );
  }
