what can i do to get this fixed?
<mat-form-field appearance="fill">
<mat-label>Choose a date</mat-label>
<input matInput [matDatepicker]="picker" formControlName="datebird" >
<mat-hint>MM/DD/YYYY</mat-hint>
<mat-datepicker-toggle matIconSuffix [for]="picker"></mat-datepicker-toggle>
<mat-datepicker touchUi #picker></mat-datepicker>
</mat-form-field>
It’s possible you have a version of material that’s not up to date. Before version 15, use and "matSuffix and not "matIconSuffix"
