Every time I think of this, I dread spending several hours re-downloading all apps (running into a few tens of GBs) from the App Store, since Apple removed the ability to sync apps into iTunes, and later removed the apps section from the latest major release of iTunes without providing a replacement. I don't like this specific attitude with Apple, where decisions are made without considering the state of Internet connectivity, speeds, reliability, etc., around the world.

Edit: You have to be on WiFi to get this done, even if you're in a place that has great cellular data speeds and high data download limits, because iOS won't allow downloads of apps larger than 150MB (IIRC) on a cellular connection.

Interesting, was thinking the lock screen issue had to do with me not using touch id. They did fix it inadvertently on 11.2 but then broke again in 11.2.1.
