Hi there George. My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers. It would be my pleasure to assist you with this. In order to best help you I will need to ask a few questions. First, what type of notifications were you getting previously that you are not getting now? Notifications for text messages, Notifications for new emails, notifications from apps? Also, can you please tap on SETTINGS > GENERAL > ABOUT > and VERSION and let me know what you see there. Please let me know and I will walk you through checking the appropriate settings.
