Likely what you did is try to open it on all devices at the same time and that confused things.
So, one thing at a time.
On the phone (where the dives are gone), please go to settings->advanced and enable developer mode
Then go to the Developer menu and tap on "Access local cloud cache dirs"
Can you send a screenshot of what you see there?
On Windows, can you please go to the folder indicated - and create a zip file of that folder (so the easiest is to go to the cloudstorage folder and then create a zip file of the folder ending in "208.1").
Please send me that zip file in email (dirk @ hohndel dot org).
I can then easily make sure that everything that you had on Windows ends up in your cloud storage.
Thanks
