Angular does not work by mobile browser

Question

I am trying to save a form by mobile browser (Chrome and Opera), however, after filling the data and ask to save nothing happens, the form is not submitted, the request does not arrive even in the backend and I have no validation in the form.
The Cancel button works, redirects me to another "/list" screen, where I should display a table with the entries made, but the table is displayed without any information.

By desktop everything is working, both the registration and listing of those who were registered.

Can anyone tell me why this happens?
I’m using Angular 7.1.4

For the form Ubmit I have tried to use button and input, but neither worked, nor putting (click)="onsubmit()" right on the button worked.

Template.

<form [formGroup]="formPessoa" 
      (ngSubmit)="onSubmit()" >

 <div class="form-group">
<label for="nome">Nome</label>
<input type="text" class="form-control" 
      name="name" id="nome" 
formControlName="nome">
</div>

<div class="form-group">
<label for="nome">CPF</label>
<input type="number" class="form-control"name="cpf" id="cpf" formControlName="cpf">
</div>

 .
 . restante do formulário
 .

<button type="submit" class="btn btn-primary 
mt-4" value="Salvar"  >Salvar</button>
  <button type="button" class="btn btn- 
 secondary mt-4 ml-2" 
(click)="goToList()">Cancelar</button>
     <button type="submit">Submit</button>

</form>
