It was still happening just a few hours ago. I'll check tomorrow moring if this one's solved.
I think Apple fixed the issue last night. All updates are working fine. In case if it doesnt update, restart the iphone or ipad and try the updates. Worked for me. Hope it works for you all.
I still saw this happening today so I'm not going to hold my breath. Especially since engineering hasn't even issued any bulletins yet on a fix. Rumour has it that this is related to one pod in particular. But I'm always suspect of rumours.
