I brought Neo 9 pro from Amazon and started using from two days. Yesterday I noticed, that after certain number of notifications from few apps like Microsoft Teams and Microsoft outlook, I am not getting notifications after surtain number of Notifications but when we open those apps we can see new mails and new chats. Seems like it is due to notification per day, notification per week number. 

Is there to over come those selecting and get all notifications at all time?

As a IT employee, it's important to get all notifications from Teams and Outlook.

Please let me know how to fix it
