Versa App Notifications not working

[SGAngel]

My app notifications, such as FB Messenger, Facebook, Gmail, and Calendar were working about 3 days ago.  However, now I am not getting them.  I have a IPhone 6plus.  I have done all the suggestions I have read, such as unpairing, turning off bluetooth, shutting off the phone and Versa and restarting everything.  I have also check on my Versa that notifications have been turned on.  On my phone, I have checked my do not disturb and that the app notifications I wish to receive have been completely turned on under settings.

When I to into the Fitbit app to turn on app notifications, it states: "apps will be added to the list after they send notifications to your phone."  I am assuming that means I have to wait until one of the apps send my phone a notification, and then I can choose it from the list.  Is that correct?  

But why did my notifications turn off in the first place?  I just got my Versa before Christmas and everything went wonderfully pairing my phone with my Versa.  However, when I went to set the Windows 10 Fitbit app with the versa, I couldn't download music and was told through a customer service agent that they are working on resolving this issue.

Not knowing much about iOS, I've noticed with phone or Fitbit app updates permissions sometimes get reset.

Have you checked the permisdions on the phone? Does Fitbit have permission to your phones notification panel?

Have you checked Fitbits setup guide and troubleshooting steps?

How do I get notifications from my phone on my Fitbit device?

Receive call, text message, calendar, and other notifications on your Fitbit watch or tracker if you have a compatible phone.

I have gone through both articles you have and tried everything. I don’t
see a list of apps like Facebook, FB Messenger, or gmail on the list to
turn on. I have gone into my setting notifications and made sure these are
all showing up in my lock screen, banners, and notifications screen but
still nothing in the app.
As an example of this... the gmail you sent me show on my phone, but I not
on my Fitbit app list to add.

I have searching for solutions, and I read to unpair from bluetooth, then remove app on phone.  Reboot phone. Turn off watch ad back on, until FitBit icon comes up.  Then reload Fitbit app on phone and reconnect  bluetooth.  I did that, and I now have the fitbit app notifications, but I still do not see any for my gmail, facebook, facebook messenger.  

What else should I do?

Just so others know, and thank you staff at Fitbit for assistance, this worked for me!!

Un-pair watch on phone.

Remove Fitbit app from phone.

Reboot phone.

Reboot watch, holding left and bottom button, until the Fitbit logo comes up on the watch.

Download the Fitbit app on your phone.

Login to your Fitbit account, and accept all permissions.

Connect your watch.

When I went into the App Notifications on the Fitbit app on my phone, the FitBit app notification was there. I turned it on.

Now, my app notifications (such as gmail, FB messenger, FB) did not give me an option to turn on until I started receiving those notifications on my phone.  So I sent my self a text email, and when it came on my phone, I went to the FitBit app and turn the gmail notification on.  I did this for all other apps I wanted notifications for.
