@tytanick Same issue here. I have to authenticate with the 1password app and with Opera, but touch ID works with the app: for Opera I have to enter two passwords, one for my company account and one for my personal account. With Chrome, the integration is seamless: authenticate with the app and both 1password accounts are automatically unlocked.
It's a big enough issue that I switched back to Chrome on my work laptop and am close to switching on my personal laptop as well.
