Hey there!
Have you already checked the Notification settings you’ve selected for each of the apps that you mentioned is still vibrating?
You can swipe down and swipe left on the notification to display the Settings Gear Icon.
Once you’ve selected the Icon, it will open the apps notification settings and display what option was triggered.
You have options to set the notification to Alert, Silent, Vibrate and show as a pop-up if the application allows.
I would recommend using that pathway to check the apps that are still vibrating to see if the option to disable is available. If it is not available, I would recommend reaching out to the application developers directly. You can locate their contact information on the application download page.
I hope this message finds you well!
