The discussion for all new features in Beta should be done here, to have together in one place all opinions.
I announced its removal near two months ago, due to many complaints, without responses.
We cannot have mandatory the “Route missed” message as several don’t like it (or their GPS causes troubles). And filling the app with another on/off option is also not very intuitive.
A thought is that when the new (repeated) off route notification is off, then the “Route missed” is announced once.
