Its a problem with eBay. They don't have an option to shut off vibration notifications. I've sent an email to eBay regarding it, its very annoying. Especially when you have 15 items listed at a time...Anyone know how to eliminate the double vibaration on my lockscreen when alerts from eBay come on display. I've looked in the App itself and can't for the life of me find anything for 'Vibration' (only sounds).
