I am having a problem with being able to delete some data out of my iCloud storage. On my iPhone or iPad, I'm going to 'Manage Storage' and trying to delete data from iCloud Drive/Other Documents, iMovie, Alto's Adventure, and Siri, but nothing happens after deleting - it just stays on that screen and still shows that they have data if I go back and refresh. (I was able to delete some other categories earlier.) The same thing also happens when trying to do it on my Mac. It just says that it couldn't be deleted and "Try Again Later". My iCloud Drive or iMovie have no visible documents in those apps, but they both show as having less than 1 MB of data. I know it's nothing to worry about given the low amount of storage they're taking up, but it seems like I should still be able to delete everything. Is this a common problem, or known issue? Any workarounds?
