Updating this topic myself:

  1. I believe Firefox (148) does not support the Cross-Device Authentification, but I have not read to confirm.
  2. After some investigation, I have come further. 1Password app for Android requires Android 14 for this to work. I have not tested on /e/OS Android 14, as my mobile with /e/OS is older and only has Android 12. But during this time period since I asked the question, I have switched to a mobile having Iodé OS (another "de-googled" Android) based on Android 15. As for now, it appears as cross-device authentification is not working yet with microG (replacing Google Play Services). So my issue is likely related to the fact that I use a de-googled Android. For anyone interested, you can read my post at the Iodé community and the bug report at the microG github:
