The reason why you may see your withdrawal address locked is this: security.
After the first time a withdrawal address gets used, it also gets locked for 24 hours. This security feature was implemented in case someone got access to your wallet - and you didn't whitelist your withdrawal address(es) - so they wouldn't be able to withdraw your coins right away.
Your withdrawal address will also get locked for 24 hours each time you change it. Once the 24 hour lock period is up, you can withdraw your coins as normal.
In order to change the withdraw address, please follow these steps.
1. Open the app. If you don't have a wallet yet, please follow our guide on how to set up your Celsius wallet.
2. Tap on the Celsius logo in the bottom right corner.
3. Tap on the "Profile" button.
4. Tap on the "Security" button.
5. Tap on the "Change withdrawal addresses" button.
6. Here you can change your withdrawal address for each coin. Again, note that once you change it, the address will be locked for 24 hours and you can only withdraw your coins after that time has passed.
Tap on the "Change" button for the desired coin you wish to change the withdrawal address.
7. Enter your "2FA/PIN verification code".
8. Input the new address that you wish to use or scan the QR Code by clicking on the link and using your camera.
Next, click on the "Confirm" button.
9. Double-check the address and tap on "Confirm" again.
10. After you tap on "Confirm" you will get a message that you need to confirm this change via email.
On the next page you can add a label to your address to make it more easily identifiable. After this, tap on the "Finish" button.
11. An email has then been sent to the email address under which your wallet is registered. On it you will be able to confirm or deny the address change.
If you did not request the change, you're also able to freeze your wallet in that same email.
12. Click on the "Confirm Address Change" button.
And that's it! All done!
