Sometimes users need a clean reinstall of the Jaxx Liberty Wallet. To do that please follow the below steps:
1. For full safety, you need to save a copy of your 12-word Backup Phrase. Once you will reinstall Jaxx, you will need the 12 words to pair your wallet back.
You can find the Backup Phrase here: MENU > Security > View Backup Phrase
Only when you have the 12-word Backup Phrase copied to a safe place and 100% correct, move on to the next steps.
2. Now you can uninstall and then reinstall your Jaxx Liberty app. Make sure it's the latest version from here: https://jaxx.io/downloads
3. Once that is installed again you'll be asked to "Restore Interface". Follow the process and enter the backup phrase to pair your Jaxx Liberty Wallet. If you missed that step you can go to Menu > Tools > Pair/Restore Existing Wallet > Enter Password (if one is set) > Continue to Pair or Restore Wallet > Overwrite Back Phrase > Continue > Enter your 12 word backup phrase > Restore Wallet
