COMPLETELY purging "Messages in iCloud" without waiting 30 days - will this work?

Hello,

I thought we could put our heads together to try and figure this one out. I'm having a heck of a time because the support staff at Apple doesn't appear to be fully trained on how 'Messages in iCloud' works.

The problem:

I originally 'enabled' Messages in iCloud' back in April when it was still in beta. Text messages on my phone were pushed to the cloud, however it became corrupted and some of my oldest messages were displaying incorrectly, now on both my phone and my MAC. After doing some SQL editing, I figured out that the older messages had become duplicated. I manually FIXED this, recently. Now, both my phone and my MAC have correct versions of my text message libraries.

'Messages in iCloud' is turned off, because if I enable it, the system will attempt to push the corrupted archive (sitting in the cloud) to either my phone or MAC. The only way to purge the archive in the cloud is to "Disable and delete" it, but it doesn't fully purge for 30 days. There is no way to delete it on-demand like you can with an iCloud backup.

I have been on the phone with Apple multiple times and it takes me 20-30 minutes just to try and explain this problem to them. And then they keep telling me that 'messages in iCloud' get replaced by iCloud backups - not true.

So what I want to do (in order to expedite the deletion and not have to wait 30 days...):

1. Enable 'Messages in iCloud' on a secondary iPhone - let the corrupt archive in the cloud download to that phone.

2. On the secondary phone, once all messages have been downloaded, DELETE all messages on my phone.

3. Wait for the deletion to sync up with the cloud.

4. When the cloud archive is deleted, begin a fresh re-upload.

What I fear may happen (and I would like someone to confirm) is that when I attempt step 4, the fresh messages on my main phone will get deleted because the cloud will try and sync with my phone (post-being deleted from the secondary phone) and will try to propagate the deletion process to my main phone.

Can someone help?

Bob
