New Clicking/Popping Sound

[RicKaysen]

Today, the Edge started making random notification sounds. It's a soft, three clicks or pops. They don't appear to be related to any messages or pop ups. The only thing that's new is I enabled Samsung Pay, but I don't see any activity related to that. I know it isn't much to go on, but in case anyone else hears it, maybe you could tell me how to stop it. TIA
