Please make sure you have a backup before updating the app. Critical fix allowing to unlock access to bitcoins for those who updated from version 1.0 to 1.1 and had their funds locked out. Users who created new wallet in v1.1 must use backup to restore access to funds. The app will automatically detect if the wallet needs restore on Receive, Send, Cold Storage and Backup screens. You will be able to enter the backup phrase when prompted without the need to re-install the wallet. Backing up is required when creating a new wallet. Added reminders for existing users to back up.
