If the route is already on your device (and it has exactly that name), it will be loaded as navigation route. If you use navigation routes that contain special language specific characters, you may get into trouble here because those routes might be stored without there characters.
The red entries in the Training Log are just the trainings you should do. It's normal that an extra entry (in blue) is created when you start the training. Red entries are just reminders.
I try to use feature called trainning plans. I prepared trainning plan to my phone and ok: I have new activities in red colour. Observed that there is 1 hour time difference (I'm not sure its importnt).
When I click on planned trainning there is an option to start new trainning I choose it, but It start just new trainning not trainning in my trainning plan (the trainning title deleted). What I do wrong?
