I searched this forum and Reddit and can't find help. I'm incredibly frustrated after a year of owning this phone. When my screen is locked, the ONLY notification I will receive is a text from the Samsung App. I use Instagram, Facebook, Twitter, Outlook, etc. If I have a new notification from these apps, the phone will not notify me if the phone is locked. Every so often, I will pick up my phone, unlock it and then I get a BARRAGE of notifications from all these apps. Why is it doing this? 

Running Android 13

Lock Screen Always On Display is = ON

Lock Screen Notifications is = ON with "Show Content"
