Hi please excuse my lack of knowledge as im not a developer but a customer trying to find a solution to a problem my developer is having.
We are buiding a hybrid app with geo fencing and we are trying to use a custom mp3 for our notification. It would not let us use a custom one and when we changed it it would crash the app. They said they cant find a solution but I cant help but think this is something alot of people would want to do and there must be a solution to fix this.
