No way to find or create a "recovery code"
I am signed i to my Tutanota email account on my computer, and Nowhere can I find ay way to access, or any reference to, a "recovery code". I tried changing my password in the hope that I would be offered access to a recovery code, but it didn't happen. I really like Tutanota, and this "recovery code" is a great idea, but you seem to be claiming to offer a "service" which Does Not Exist! If it does exist, why not make it available to current users?
If you can’t find the feature, you are probably using the old client. Please login via https://mail.tutanota.com.
