Error "Oops! Track not available": why and what should I do?
This message could appear for several reasons.
The main one, during Missions, could be that the song you're trying to listen to is not playable in your Country.
What can you do?
Simply ignore the song. The task will stay in the "In progress" tab for a while, then it will go back to "All tasks".
When this can also happen?
If the track that you want to edit by clicking on the "Start" button is already loaded in Spotify sometimes you'll get an error saying "Oops! Track not available".
In this case, please try to tap on the Spotify "Play" button related to the same song or try to play another song and go back to the list of tasks, go to the "In progress" tab and click "Edit" on the same task as before.
Sometimes when you click "Start" or "Edit" on a task Spotify will start playing the song but the Musixmatch app will keep loading and eventually give you the error message "Oops! Track not available".
You can try to go back and apply the same workaround as in the case above.
