Hi, thank you for created this template.
You should also add `:turbo_stream` into `config.navigational_formats`, because without that it doesn't re-render the view in all my case.
i got it from https://gorails.com/episodes/devise-hotwire-turbo

Thank you  I've updated that to fix that case too!

Hi, Andrea, I'm using this for your course. Have the Devise issues been resolved in the latest version? Is there an updated Railsbyte, if so?
