Thank you for your reply.
By global sttings i mean my phone ringtone settings. I have my phone to never vibrate on anything but whatsapp still vibrates on incoming messages even when its notification setting is set to "Default".
I already tried what you suggested but when I do it whatsapp will not vibrate when I set my phone on vibrate mode. Everything else will vibrate except Whatsapp. I set my phone to vibrate in my pocket when I'm working.
I have read on google play store that many users started having the problem after the last update.
I can downgrade Whatsapp by uninstalling and reinstalling the previous version via Aptoide but I'm afraid to be removed from the Whatsapp groups I have created and those I'm in.
Thank you kindly.
