I did an update to the latest iTunes yesterday, and after the update and on startup, a window popped up that said "apps" are no longer managed thru iTunes and only online thru the store (paraphrasing). This makes the instruction for
Go offline—Collector for ArcGIS | ArcGIS obsolete. I could also not find the mapped iPad in my File Explorer.
So I think that would also break the instructions for copying a .tpk directly to you device as explained
Prepare basemaps for offline use—Survey123 for ArcGIS | ArcGIS and may affect use of other esri apps offline too.
Has anyone found a work around for this? Am I the only one with this issue?
Note: older ipad (ios 9.x...can't upgrade to 10.x)...tried on both a Win7 and win10 machine. I did not log into the itunes store when I tested.
