[iOS] How private messages in the app work
The private messages can be accessed via Account&settings menu of the app.
If you have a new message, you will see a notification on the main app's screen.
To start a new dialog, you need to find the profile of the user you'd like to talk to using this instruction.
To delete a chat, please tap the trash bin icon on the dialog list.
Please note that your account's email must be verified to use private messages.
