My Samsung S20 FE Vibrates Randomly Using Snapchat

I have a Samsung Galaxy S20 FE, and I'm seriously frustrated because it randomly vibrates whenever I use Snapchat, as if there's a notification—but there's nothing there! I've repeatedly checked notification settings, uninstalled and reinstalled the app, and restarted my phone multiple times, yet this annoying issue persists. Additionally, the vibrations disrupt my daily use, making it impossible to comfortably use Snapchat or my phone. Considering the premium price I paid, I didn't expect such a bothersome issue from a respected brand like Samsung. It's extremely disappointing that such a basic software issue hasn't been addressed properly.
