It appears every few times I open the app and the usual android back button doesn’t make it go away, and there is no cancel button. What you have to do is toggle the toggle, then the button will change to “do not back up” and then you can press it. It annoys me how easy this makes it to accidentally turn on backup.
Maybe, the average user really doesn’t understand backups though and would be more likely to ignore it then.
That’s too bad for them, but at a certain point, people should be expected to have some level of understanding of the technology they are using. Giving people the information via a highly visible yet unobtrusive notification is more than enough to guide people that don’t understand. If they decide not to follow the clear instructions then that’s on them.
It’s kind of like no child left behind. In theory, it’s a good idea to make sure everyone is in a good position for success, but it’s not good in execution because it negatively impacts more than it helps.
