Hey so before this most recent update, my phone would vibrate when I got a facebook alert. This would only happen when my phone was on vibrate, now no matter what setting I have it on it doesn't do anything. I was trying to figure out how to change this but couldn't find anything. Any help would be greatly appreciated.
Go to your Profiles, pick which one to edit, & scroll down to the "+Other". Click on it, & Facebook should be listed under there. It is for me, so I'm sure that's how you can enable it to vibrate?
