Signing in on multiple devices

Most people end up signed in to Cradle on more than one device, the work laptop and the mobile is the common pair, sometimes a home computer too. Cradle is designed for that. There are a couple of behaviours worth knowing about so you don't get caught out.

What works the way you'd expect

You can be signed in on a work laptop, a home computer, and the Cradle mobile app at the same time on the same account.
Your call log, contacts, voicemail, and call recordings sync across every device you're signed in on.
Outbound calls work from any device. Pick up the one in front of you.
The mobile app rings when you have an inbound call, the same as the desktop, provided your presence allows it.

Presence is one state per person, not per device

There's only one presence for your Cradle account. If you're Available on your desktop, you're Available on your mobile too. Two devices don't make you "more available" or send two rings to the same caller.

The desktop is the source of truth for presence, mobile follows along. Read How does presence work? for the full story; the short version is:

Changes you make on the desktop ripple to your mobile.
The mobile app won't automatically set you to Idle or Offline, that's a desktop-side behaviour.
On a call is set automatically on whichever device you're calling from.

If you want to be reachable while you're away from your desk, leave the desktop signed in and Available, and have the mobile app installed and signed in too. Calls will reach you on either device.

Two desktops can pull on each other

If you're signed in on a work laptop and a home computer at the same time, the presence settings on both will fight each other a bit. The most common symptom is presence flipping back to Idle because the unattended computer hasn't seen activity in a while.

The fix is simple:

Quit Cradle on the computer you're not using. Quitting sets it Offline so it stops voting on your presence.
Or leave both running and accept that presence will track whichever computer you used most recently.

If you have a specific reason to stay signed in on both (you switch between them mid-day), check Automatically set me to away after on each. Setting it to Never on the secondary machine stops it from pulling you to Idle.

Signing in on a second machine

You don't need to sign out of your existing computer before signing in on a new one. Open Cradle on the new machine, sign in with Log in with Google or Log in with Microsoft as you would the first time, and you're in.

What happens to the old machine afterwards can vary. In some cases the old desktop continues running alongside the new one. In others it'll prompt or sign out shortly after, when its token gets invalidated. If your old computer suddenly shows Your session has expired after you sign in on a new one, that's the most likely cause, see Your session has expired.

If you've finished with the old machine for good, the cleanest thing to do is to sign out from it intentionally. See Signing out and switching accounts.

Mobile signed in alongside desktop

Mobile and desktop are designed to coexist on the same account. Signing in to the mobile app doesn't sign out your desktop, and vice versa.

Install the Cradle iOS app or Cradle Android app from the store.
Sign in with the same Google or Microsoft work account you use on the desktop.
Presence stays on whatever the desktop is set to, see "Presence is one state per person" above.

If you only use Cradle on mobile (no desktop signed in), your mobile becomes the authoritative device. Read the mobile section in How does presence work? for the full picture.

What you should see

Each device shows your name, presence, and call log identically.
The team screen shows you once, with one presence dot, regardless of how many devices you're signed in on.
An inbound call lights up every device that's eligible to ring. Picking up on one ends the ring on the others.

If something looks off

My presence keeps changing on its own. Likely two-desktop drift. Quit Cradle on the device you're not using.
A new sign-in killed my old session. This is normal in some cases. Sign in again on the device you want to keep, see Your session has expired.
My mobile isn't ringing even though my desktop is. Check the phone's OS-level Do Not Disturb or Focus mode. The phone OS can decline a Cradle call before the app gets a chance to ring, and that's separate from Cradle presence. See Why am I not receiving calls?.
