Hi, I finally upgraded from Android 7.1 to a new phone with Android 13 two weeks ago, and in the next few days tried out my 250+ apps one by one.
Navigator told me about a licence problem - "cause is frequently a new Android version" and asked if I wanted to solve the problem, which I did. I was told there should be a solution within 24 hours.
I waited two days, started Navigator, same message.
Since then I have been starting Navigator once a day - always the same message (to which I always reply, re-sending my email address as required by the second message, after I tapped on "Yes").
