Are you experiencing an issue when you sync CrewBuddy to your google account and it automatically adds an email notification and a phone alarm notification ?
Solution:CrewBuddy isn't the one adding those notifications. When CrewBuddy adds a new event, one of your other programs or services sees that new event and attaches a default notification to it. Most often the culprit is Google itself.
