Sense 2 is not receiving notifications

[AmyPie]

My Sense 2 watch, paired with Samsung phone, stopped receiving any notifications. It had always worked fine before.

At first the watch stopped syncing to the phone at all - after restarting the watch to fix that, it came back as if brand new/had to set up from scratch. It did then sync fine, but has not received any notifications, ever since.

I have followed all troubleshooting steps on help centre and previous forum threads:

Restarted both phone + watch, forgot and reconnected on Bluetooth, checked all settings for notifications are turned on, etc.

What else can I do??

Hi @AmyPie. Welcome back to the community forums.

Thank you for taking the time to share the information regarding this difficulty that you have with Sense 2. Thank you for trying to fix it on your own. 

Since you mentioned that you were having syncing issues, please take a look at the points listed in this help article: 

Why won't my Fitbit device sync?

Even if you already tried many troubleshooting steps listed in other help sites, I suggest you to confirm that you have followed the steps as indicated in this help article:

 Why are notifications delayed or missing.

Thanks for your reply but still no notifications.

I had already done almost all the steps in those two articles; I have done them all again, in the order suggested, including deleting and re-installing the fitbit app.

But still nothing. 

I believe there was a recent update to fitbit around the time this issue started - is it possible to revert to the previous version?

And/or who else can I contact to fix this?

I am missing calls and messages because of this issue and really need to get it working
