Last night I updated my devices to iOS and iPadOS 18.4.
This morning I used cobalt.tools to download an interesting video about the oldest known trousers in existence (don't ask).
Anyway, as safari was slurping up the 500mb of this video, I noticed a new icon in the top-right corner of my iPad screen.
This icon stayed visible all while my download was active.
Then, it stayed visible as my upload was active. I uploaded this file to a folder on my iCloud.
Now, both the up and downloading of the video file are complete, and the icon is still visible. Maybe this is a safety feature? Like the GPS 'arrow' that stays visible for some minutes after the location services where used to signal the user that one on my apps asked for my location?
I found this list of 71 new features that are part of iOS/iPadOS 18.4 but this one isn't on the list. Maybe they missed something, or am I misunderstanding this icon? Please let me know your thoughts 😅
Addendum: some more Kagi kungfu revealed that this icon means something completely different than what I guesses at: "this icon is an icon indicator that the iPad is on the process of syncing and finalizing the software update."
