What a load of bollocks. There seems to be a inherent bug here.

Fix it.

Poor responses from apple

When you get a popup message on your iPhone or iPad that the storage is full.

Look closely storage of iPhone and iCloud.

If you are a level ten advisor, and this is your advice then apple, apple's support, apple's 3rd party support model and yourself seriously need enterprise level help.

Wow.

Apple seem to be very quiet on this matter. All I hear is buy more storage yet they then say that may not fix this issue.

Think apple don't fully test updates and are more prone to software security flaws
