Hi Julie, I’ve just released version 1.6.3 with the following changes:
* Fixed setting default values to new registers.
* Fixed direct opt-out reply link not unsubscribing topics.
* Fixed legacy opt-out setting not being correctly applied to model at times.
* Fixed inexisting property notice in settings model.
* Updated pot file.
* Improved direct opt-out messages.
* Improved opt-out explanations in settings.
I believe that covers all your points and more. Do let me know if I missed something.
