T:TTS Service error, code -7

I recently had a very strange problem with the voice output during navigation. When setting off on a planned hike, I launched Track Navigation as usual and an orange error message appeared: “T:TTS Service error, code -7”.

I tried the usual quick fixes: restarting the app, clearing the cache, restarting the device, moving the TTS file so that a new one would be created, and reinstalling the app, but none of it helped. This error message appeared every time I started the navigation.

In the end, we set off on our hike without any voice instructions; the navigation itself was working, just without the voice prompts. So I had to keep looking at the screen. After about an hour and a half, or 5 to 6 km, I suddenly and quite unexpectedly heard a voice instruction. A miracle cure? From that moment on, everything ran smoothly again, even after restarting the navigation or the app. So it seems to have been a temporary problem – hopefully a one-off. Nevertheless, I’d have liked to know what might have caused it. Attached is a screenshot of the message.
