Will you be happy to have an app without notifications support for your project ? Is notifications important to you ?
As an end user, I prefer to mute certain apps for its annoying notifications. But for some apps like those used for messaging, notifications are fine. Even Facebook does too much notifications. I have to try and mute it if possible. There is a very thin line between notifications becomes annoying and useful notifications. Just like ads on websites, people might soon opt for notification blockers. Since the end user and project manager has different views about notifications, is it possible find a balance between these and make conversions out of notifications ?
