With 11.89 turn-by-turn navigation is still not working. When importing a .gpx file as course and select it in running activity, you will see the course on the map, however there is no vibration or voice alert when I need to make turns. It does tell me when I'm off-course and when a lap has passed. I'm forced to use Komoot which does have this working correctly, but I rather not... Sad that it has to take this long to fix.
