Fast answer
The answer before the background
For hungry shark world lost all progress, stop reinstalling and identify the device, operating system, store account and cloud icon state. Ubisoft says supported transfers work only within the same OS: Android to Android or iOS to iOS, not Android to iOS. Sign into the original Google Play, Apple or Facebook account, enable Cloud Save, and inspect any conflict carefully because choosing one save erases the alternative. Contact official support with the cloud ID and purchase evidence when needed.
Recovery order
Move from evidence collection to reversible checks
| Step | Action | Do not do yet |
|---|---|---|
| 1. Identify | Device, OS, store account, game version and last good date | Do not create several new guest runs. |
| 2. Preserve | Screenshot cloud icon, user ID, balance and receipts | Do not delete app data. |
| 3. Reconnect | Use the original supported Google, Apple or Facebook identity | Do not test random social accounts. |
| 4. Resolve | Compare conflicting save progress before selection | Do not tap through; one option is erased. |
| 5. Escalate | Send official support the evidence it requests | Do not upload credentials to a recovery seller. |
Transfer boundary
Same operating system is the supported route
Ubisoft's transfer article explicitly says Cloud Save can move progress when old and new devices use the same operating system. Android and iOS are different systems, so a direct transfer between them is not supported. A Facebook sign-in option on both platforms does not override that published boundary.
Console progress belongs to Xbox, PlayStation or Nintendo account and cloud rules. A mobile cloud ID is not proof that a PS4 or Switch save can import. Keep support cases separate and use the platform that owns the license and save container.
Loading and login
Fix the clean official client before touching the save
For a loading screen or failed Facebook login, confirm network, store update, free storage, automatic date and correct account. Restart the official app and platform services. If the title opens on a new profile, do not continue far enough to overwrite a recoverable cloud state; capture the behavior and contact support.
Camera zoom and controller questions are interface issues, not account failures. Record device, orientation, input method and expected setting. An account for sale or remote recovery service introduces another login, cloud state and payment risk. Quest Meridian provides no marketplace or credential handoff.
FAQ
Common questions
Can I transfer Android progress to iPhone?
No under Ubisoft's current published rule; Cloud Save transfer is supported only between devices on the same operating system.
What if two saves appear?
Compare them carefully. Ubisoft warns that choosing one erases the alternative progress option.
Should I reinstall when the game will not load?
Not before confirming cloud state and preserving IDs or receipts; local progress can be lost.
Where should I ask for help?
Use Ubisoft Mobile's official Hungry Shark World support center and the relevant platform owner.
