Hi @hinder90,
I believe you already discovered this, but Amazon resolved their issue today (I need to take a look at your other post, too).
For mode and ownership, odrive does not persist those attributes on any integration, currently. I believe it would be possible using the custom attributes abilities that some integrations, like Google Drive, offer. It just hasn’t been an oft-requested feature, so it hasn’t made it onto the roadmap.
iCloud’s lack of a published, public API for general cloud storage access is preventing that integration from happening. I doubt they will provide one, but you never know.
