Fast answer
The answer before the background
For a jurassic world the game facebook login problem, stop before unlinking, reinstalling or creating repeated guest parks. Record the support key visible in Settings, the platform, device model and last known account method. Facebook-connected progress is server-accessible on compatible devices; a Guest save is local. Ludia says a Guest transfer can be handled manually when support receives the old and new support keys, and the completed transfer removes access from the original device.
Preserve
Capture identity before changing the installation
Take a screenshot of the support key, park name, level, recent purchase receipts and the exact login choice shown. A support key is sensitive recovery information; send it only through the in-game help flow or verified Ludia support, never in a public comment, marketplace chat or supposed account-fixer form.
If the app still opens, allow the account service to settle before switching Facebook, Apple or Google Play identities. A blank guest park does not prove the old data was erased. It may mean the client opened a different identity path. Repeated unlinking makes the evidence harder to follow.
Transfer
Guest, Facebook and platform identities behave differently
| State | Where progress is associated | Recovery move |
|---|---|---|
| Guest | Local device data | Keep the old install and contact support with both support keys. |
| Facebook-connected | Server-linked compatible account | Verify the correct Facebook identity before loading. |
| Apple / Google Play | Platform-dependent sign-in | Use the matching store account and current support instructions. |
| Modded or purchased account | Untrusted ownership chain | Do not send payment, passwords or support keys; official recovery may be impossible. |
Crash triage
Protect the save before troubleshooting the app
Check the current known-issues page, free storage, operating-system compatibility, network stability and store update first. Restart the device and test the official build. Reinstallation belongs late in the sequence, after the account is clearly linked or support has confirmed a transfer path.
A useful support request includes the support key privately, device and OS, app version, error text, time, network type and the last successful action. It does not include a guessed diagnosis. That evidence lets support distinguish a login mismatch from an outage, incompatible device, interrupted purchase or damaged local guest state.
FAQ
Common questions
Can a Guest save move to a new phone?
Not automatically. Ludia documents a manual support transfer using the support keys from the old and new installations.
Should I post my support key on Reddit?
No. Treat it as private recovery information and send it only through verified support.
Does a blank park mean my progress is gone?
Not necessarily. First verify which account method was loaded before resetting or reinstalling.
Can I keep playing on both devices after a manual transfer?
Ludia says the original device no longer has access once that Guest transfer is completed.
