I'm sorry to hear that you've had trouble with their support. We've exhausted the troubleshooting available for this issue, and would normally recommend repairs at this time. However, since your device is not a US model, we would not be able to assist with setting up repair services. I would recommend seeking a support team for your area.

I am having the same exact issue, even though my settings are properly calibrated to show notifications. Clearly this is something on your end, and not the users'
Please advise if you are working on fixing this in a later update? thanks
Both my husband and I JUST purchased brand new s9 plus' and we can't make notifications pop up on lock screen for the life of us. Have been trying everything & watched many YouTube vids and it still won't work! Very annoyed!
On the new devices (since android oreo update?) There is no option to get pop ups on the lockscreen. Its not an iPhone though. You can only see the notifications on your lockscreen, when you turn your phone on. There ja no visual effect or something. The screen doesn't switch to on by it self just through notifications. That's a bit annoying but it's like that.
