Specifically, for Windows App developers, I'm wondering about what would be the best wording for your app's Help page, when you have an app that has Live Tile updating,
I mean, you've got to convey to the User that all of a sudden, their Live tile may stop working, and what to do about it.
To be thorough, and to really cover all of the bases, you have tell the User that the Phone only has a certain number of allowable "background tasks" going on, and you can go into Settings > Advanced to block some unwanted apps, so that your app's Tile updating can work.
But then, (still talking to user), you still may need to go into Background Tasks > Advanced, to spot some apps where, you may have to either remove the app if the app doesn't have a Settings page, or go into the Settings page and turn off anything that looks like they're doing something regular in the background.
Otherwise many end users of apps ( as you can tell when you browse through windows store or apple store reviews) are kind of ruthless, and will give you a one star, if the slightest thing appears it doesn't work, and just write you off that way.
