Cannot add e-mail address and mobile number with Element IPhone App

Hi!

I cannot add e-mail address or mobile numbers to an account via Element iphone app.
It works pretty fine with element-web or element-windows app.

If I try to add an email address with my Iphone App, i get the error: "Request failed: unauthorized (401)
When trying to add a phone number there is no error message, but the number will not be added.
