Hello and welcome to the Fitbit Community @Krigarra
I understand you’re not receiving notifications at this time. (But you are receiving calendar notifications) The question you ask is a tough one about updating to iOS 13. I can’t promise that updating to the iOS 13 will provide you with all notifications. But at this point staying at iOS 12.4 is not providing you notifications either so I really see no point in trying to hold off. Updating is a personal choice so it’s clearly up to you. If you want to go ahead and update to iOS 13 I would do so first and if your still not receiving notifications try this after you update:
Go to your Bluetooth and remove your Fitbit Tracker and tap “Forget this Device”
From Fitbit App tap profile picture, then scroll down and tap your Fitbit Name, then scroll down tap “remove device”
Now log out of the Fitbit App, then force shut the App by swiping the app upward
Now turn off your Bluetooth and your internet connection on your iOS device
Now turn off your iOS device completely, wait 1-2 mins then restart your iOS device
Turn your Bluetooth back on and reconnect to your internet
Log back into your Fitbit App as you normally would with your email address and password
Now tap your profile picture then scroll down and tap “Set up a Device”
Chose your Fitbit Tracker type from the list and just follow the instructions carefully
Go to your Bluetooth settings and tap the small “ i “ to the right of your Fitbit Tracker name and make sure “Shared Notifications” are enabled
Now go back to your Fitbit App, tap profile picture, scroll down and tap your Fitbit Device name, now scroll down and tap “notifications” and ensure all the notifications you want are enabled.
Tap “Today” at the bottom of your screen to return to the main page of the Fitbit App
Sync your Fitbit Device
**now try sending yourself a text and have a friend call you to see if your notifications are now working
😃 Let me know how it goes
