Hi. If you check the previous story, you’ll see that this problem has affected quite a few of us. People tried a variety of fixes. Some fixes worked for a few people but not for all. Most of us eventually seem to have been able to update...after many downloads, deletes, force restarts, etc. Just give it another go, even do what I did and select ‘Remind me later’ and update when you get the reminder...mine worked fine in the end. Lots of theories about what’s been happening. Most popular suggestion is a server issue at Apple’s end. Anyway, give it another go and see if it works for you.
