We are working to fix the following two problems on iOS:
Touch ID and Face ID working again
The problem where Face ID and Touch ID did not work anymore has been resolved in version 1.6.1 of the mobile app. Be sure to update your app to the latest version if you're still encountering this issue.
Problem sending crypto assets
iOS 13 has introduced a regression that leads to an error when trying to send crypto assets based on Bitcoin or Ethereum. You may either consider wait for a fixed version of the app until updating to iOS 13, or update to iOS 13 and use Ledger Live desktop to send your crypto.
We apologize for the inconvenience caused by these issues and thank you for your patience while we work to fix them as soon as we can.
