This is sort of nothing. I had assumed that the notification.schedule message param would be very limited in length. I was just fooling around and got shocked. It seems to handle a lot. My test below does 100,000 + 3 chars as a message.

Again, it's not a big deal. I just thought it would be very limited. To my surprise it's not

import ui
import notification
str = 'a' * 100000
str = str + 'xxx'
notification.schedule(str ,delay = 60)
