In the add contact option, the following errors:
  1. There is no way to convey the picture (avatar)
  2. When transmitting a URL, the database duplicates the Email fields and, accordingly, does not transmit data on the URL field in contacts
  3. Why does it obsessively require you to enter a date of birth / it is desirable to make it optional - so as not to transfer info to it
  4. Make it possible to check an existing contact and not allow creating an unlimited number of contacts to the user
