Inbox "growing" back

Following my question in

I do not think that the following is the reason:

“to avoid this please wait until all all devices have been synchronized with the new sync location for the first time, afterwards you can continue to move items from the global inbox to other databases.”

I performed the following actions (with one DB, all others would not be changed)

  1. I migrated exactly one DB from Cloudme to iCloud. I deleted the databases on my mobile devices and on my macbook.
    Then, I created the new iCloud Syncstore on my iMac and uploaded the DB from this device

  2. After sucessfuly creating the syncstore I reimported this DB on the clients by downloading/opening from the new created syncstore (step-by-step). This works fine and without problems.

The problems occurs after some day and it’s repeating regularly.

This is my installation of synced databases:

  • Global Inbox synced with dropbox (separate Sync Store)

  • 1 DB synced with dropbox (separate Sync store)

  • 3 DB synced with box (3 separate Sync Stores)

  • 2 DB synced with iCloud (one new, one migrated from CloudMe)
