First, I wanted to disable all email notifications. For each type of notification event, I had to click and disable it (while leaving in-app notifications on).
Then I wanted to install mobile app. There is "Get the app" link which is cool but when you click it, you get a prompt to enter the phone number with this message: "Note: Standard SMS fees may apply. Your phone number will not be saved."
Do I trust you that you will not save my number? I don't think so. Do I want you to give you my number? Definitely not (fully understanding that they probably already have it by accessing the contact list of all users that they gave the permission to). Why don't you email me the link to download the app, if not just giving me the link?
LinkedIn and me have not started on good terms.
