I have the FE as well & am having the problem. I get no notification, then all of a sudden hours later 6 or 8 will come all at once (or until I open the app).....FB, IG, Voicemail, even Domino's to track my dinner order. Never had a problem until I got this phone
Is there any update on this topic this keeps getting worse on my phone. Clearing Cache rebooting works as a temporary fix. @Samsung needs to do something here or give us all refund this is not acceptable performance for a phone that costs north of $500. Starting to make me think my Apple friends made the right choice this feels like trash software.
