Hello @N.K.Govindraj, have a warm welcome to the Fitbit Community, it's great to have you on board. 
Thanks for joining the Forums and for sharing your question. Please note that at this moment it's not possible to delete in-app Notifications. However, some of our members have found that after uninstalling and reinstalling the app, in-app Notifications have been removed, so I would like to suggest you to try that.
Please remember to sync your Fitbit device before uninstalling the app to prevent any data loss.
I hope this can be helpful, give it a try and let us know the outcome.
