Notifications not consistent on Charge 4

[Ski-Zone-1]

Hi Fitbit,

I received my Fitbit Charge 4 in December of 2020.  I am experiencing where notifications may stop from time to time and require a open close of the Fitbit App (on iphone) and re-synch in order for them to work.  On occasion it requires a reboot of the phone and fresh start of the Fitbit App.  Ofcourse I am not aware that I am not receiving notifications until a long time has passed and I start wondering if I should have received some notifications and then after looking at my phone I realize there is an issue.  My phone is kept in close and always in the same proximity (so that is not the issue).

Asking for a moderator or Fitbit Customer Service to respond to this post and help.  It seems the App may need some tweaking.

Thank you.

Hi @Ski-Zone-1, it's nice to see you in our Community Forums. 

Thanks for the details shared in your post and for already trying to resolve the issue. Sometimes a missing requirement is the cause and I recommend confirming the steps to set up notifications and follow the troubleshooting tips in this help article: How do I get notifications from my phone on my Fitbit device?

Hope this helps!
