Welcome to the Fitbit Community @Vivían.
Thank you for sharing that you're no longer receiving notifications on your Fitbit Versa. I appreciate your efforts to resolve this. Usually a missing requirement is the cause and I recommend confirming the steps to set up notifications in this help article: How do I get notifications from my phone on my Fitbit device? Move on to the troubleshooting steps if the issue persists.
Let me know how it goes!
