Fitness tracking not working

Hi, I have got both the “Withings” and the “Google Fit” app that are allowed to access “fitness data” on my phone, mainly for getting the steps I make. In the activity authorizations page, it says that they had access in the last 24 hours, but since I had my FP5, I always had 0 steps. Is there something else to enable/disable so that the FP5 uses the accelerometer to count steps?
Thanks!
