vibration pattern for incoming texts/emails - android 6.0.1

[shadowsjc]

I have a /stock non-rooted Verizon Galaxy S5 that I updated to 6.0.1 a few days ago. Ever since the update, my phone does 2 quick buzzes in a row when I receive a new text message or email. The problem is that in Android 5, I used to get 1 long buzz for texts and emails, and 2 quick buzzes for whatsapp messages. This way it was easy to identify when I had received a whatsapp message vs. anything else.

However, now that all new alerts have 2 quick buzzes, I am no longer able to differentiate between whatsapp messages and everything else. Is there any setting that I can change to return this to the Android 5.0 functionality? Thanks
