[AC Question]

Hi, bought S7Edge in april 2017. It started off with the preview pop up notifications, i remember that I did something by which it stopped the preview pop ups.

However, dont know how, since yesterday, again started getting preview pop ups only for whats app... checked various youtube videos but they talk about going to advanced notification features and deselct the option for preview pop, however in my phone a separate option is not, disabling preview pop is merged with muting notifications (show silently option), I want to have notification sounds, just that dont want heads up / preview pop ups...

Please help
