Android version of 1Password can’t use biometric unlock – always asks for master password

Thanks, Dave! I appreciate your quick response and willingness to help.

In the meantime, I found a workaround that resolved the issue for me: I uninstalled the latest version and installed an older build ("1Password: Password Manager 8.11.0 (120-640dpi)"). Fingerprint unlock worked properly in that version. After setting everything up and confirming it worked, I updated to the latest release via Google Play. The biometric unlock has continued to work normally since then.

Hope this helps anyone else running into the same problem. Thanks again for your support!
