Hi Scott, and welcome to the community!
In addition to the potential ongoing credential-not-saved bugs, the auto-save/auto-update features have never been completely reliable. Some of us have turned these features off, opting to add or modify entries manually and using autofill to create/update passwords. For example, here are instructions on how to create a new credential:
Regarding the reset password form you mentioned, you can follow these steps:
- Click the Bitwarden extension icon (above).
- Modify the entry.
- Click the regenerate password button.
- Save entry.
- Press Ctrl-Shift-L to autofill the new password.
- Click Reset and Login.
While this method or something similar may not be as convenient as auto-update/auto-save, it tends to work reliably in most cases. I suggest you give it a try!
