There are scenarios when your LinkedIn account can get disconnected. There are several reasons for this.
You logged in from your laptop/phone around the same time when you connected your account
You keep creating new sessions
Your connection expired
High account activity
Concurrent Login
In scenarios, where you login through The Magic Drip and then create a new login from your laptop/phone, LinkedIn may disconnect our connection. This is because both logins happen from a different location, which is construed as bot behavior.
New Logins
When you do not reuse existing sessions, but logout and log back in again and again, then LinkedIn may also disconnect other sessions
Connection Expired
LinkedIn sessions are only valid for up to a year after which they will for sure expire.
High Account Activity
If you perform way too many actions without slowly ramping up, or LinkedIn notices an erratic number of actions, then LinkedIn will disconnect the session.
What to do next?
When your account disconnects, you will see a warning on your dashboard.
Simply, go back to the Integrations tab and reconnect your account, and that is it!
