LinkedIn is strict about where and how an account is signed in, so a few small habits keep the connection stable. Here's the full list — a couple of these usually explain a repeated disconnect.
Where and how you sign in
Stay signed in: Stay signed in to LinkedIn on one main computer and browser, and keep the Katie extension there. Signing in from other machines can knock out the connection Alta is using.
Use one stable network: If you need a VPN, keep it on the same region rather than switching — big location jumps look like a security risk to LinkedIn.
Avoid location mismatches: Avoid using the LinkedIn mobile app in a different city than your computer on the same day. That mismatch is a common trigger for a forced re-login.
Things that quietly end a session
Don't log out: Don't log out of LinkedIn at the end of the day — closing the tab is fine, but logging out ends the exact session Alta relies on.
Security prompts: After changing your password, or clicking "This wasn't me" / "Sign out of other sessions," just reconnect Alta once and leave it connected. Those actions end all active sessions by design.
Clear cookies: Exclude LinkedIn from any cookie clearing, and don't run Alta from an incognito window — clearing cookies deletes the LinkedIn session each time.
If LinkedIn is asking you to verify
Clear pending verifications: Open LinkedIn directly and clear every pending verification (codes, CAPTCHAs, "confirm it's you") before reconnecting. While LinkedIn is actively reviewing an account, it keeps dropping the session until it's satisfied.
Keep it to one person: Keep it to one person per LinkedIn account. Two people signing in from different places creates constant conflicts.
The Katie extension
If you need to reconnect LinkedIn: remove the current Katie Chrome extension first, refresh Alta, and then reconnect. Reconnecting on top of the old extension usually fails — clearing it out and refreshing is what lets the new connection take.
