It’s transformed! Until about 10 pm last night my 6th gen iPod Touch had be slow & sluggish, responding poorly if at all to touch input & reluctant to interact effectively between apps.
I gave a scheduled presentation at a Mac User Group meeting on how to replace or restore an iOS device. I chose to erase & restore the iPod Touch to demonstrate these processes.
There were a few hiccups early in the process but now I can report that it’s behaving like a new device again, snappier & far more responsive.
