UPDATE: A new update for the Fit Notifications app is released (version 2.9.16). It should automatically do the steps described below. An awesome bonus is that the updated app also suppresses sounds again! Give that a go!
Okay, so after some troubleshooting I identified the fix for Fitbit’s new update, which is causing major issues for all users. Unfortunately, the fix is a little involved, but the only way to fix it is for you to manually update some settings on your phone. I cannot update the “Fit Notifications” app to automatically fix this for you. Also, this will mean that the behavior will be a bit more annoying than in the past.
So, Fitbit, in all its infinite wisdom, decided that only those notifications will be forwarded to your Fitbit tracker if the notification makes a sound. Sadly, the Fit Notifications app’s notifications do not make a sound. So, therefore these notifications will not get sent to your fitness tracker. To fix this, follow the steps in the screenshots below. Please note that due to the diversity of Android phones, the settings may not be in exactly the same place for your phone. But it should be in a similar location.
Now, pull down the notification shade on your phone and find the notification from the “Fit Notifications” app. Then, do the following to it (that is, pull this notification partially to the side).
You will now receive notifications again, but it will cause a lot of annoyance due to the way Fitbit made the app work. So, now the only way to receive notifications is if your phone makes a sound. So, for every notification you receive on your phone, you will get twice as many sounds now. (UPDATE: Install the latest version of the Fit Notifications app, version 2.9.16, to get rid of sounds again!)
