Have you taken some time off from playing or would just like to recap everything you've learned and start from the beginning? Now you can with the progress reset feature. Read on to find out how to do so.
Choose the instrument you want to reset progress for under Settings → Game → Instrument.
After choosing the instrument, go to Settings → Profile → Reset level and mission progress.
After you tap/click on the Reset button, double check that you have chosen the instrument you wish to reset progress for. You can exit the screen by tapping on the X or Cancel button.
Tapping on the Reset button will take you to the following screen, where you can double check that the correct instrument is chosen. You can also still exit the screen by tapping on X or No button.
By tapping on Yes, the mission progress for your chosen instrument will be reset, and you can start over in the instrument syllabus. Tapping on X or Okay button allows you to exit the screen.
Please note that once progress is reset, it can not be reversed. Progress reset does not affect your scores played in Weekly Challenges nor songs that are not included in the instrument syllabus visible via Learn → Missions tab.
