Struggling with an iOS update. Phone has ~15 of 64Gb free. Update needs 18Gb. No easy way to free another 3Gb, apart from removing music, for which I use Doppler, which is excellent. #doppler If my photos are mirrored to the "cloud" then why can't I have my app data mirrored? (rhetorical). If my app data were treated as offloadable, in the same way the app binaries are, iOS update could simply offload a bunch of apps+appdata, install the update then put them back, leaving me with 15Gb.
