I'm pretty sure this started happening with the new mobile app. It started vibrating my phone with no sound. I fussed around with the in-app settings as well as the Android notification settings with no luck.
There were two "Motion Alerts" categories in Android. I made sure to set it to a custom sound as well as making sure the vibrate option is turned off. However the next time I get a notification all the settings are reset back to"App provided sound" and vibrate is turned on again.
I have a Galaxy S9+ on Verizon.
