this issue has been around for a year. No idea when a fix will roll out

uninstalling and reinstalling fixed double notification issue but still can't disable the vibrations. 

uninstalled and reinstalled. Fixed. 

I'm also getting double notifications on the Android app (pixel original). I also can't turn off the vibrations...

any updates/ETA on this? Still having inability to turn off vibrate. 

Do the developers even care about feedback?
