Thanks @Tony, I understand that the auth problem is out of your control. I was hoping there was some other way to authenticate against the account somehow. The reason for my using Amazon auth in the first place is convoluted and no longer relevant. If the account is sealed until Amazon resolves this, then I guess those are the breaks. It is worth asking if you can see the other account (user “darfnader”) and whether it has any value for the price break on odrive2 Premium or not. Otherwise it’s just about retaining my esteemed identity on your forums. 
I actually misspoke about Dropbox supporting file mode and ownership. I actually am the this guy from 2017 but I discovered that Google Drive must be able to support this since ocamlfuse which uses google drive supports mode and ownership. Does odrive2 as well?
Finally, is iCloud support ever going to happen or does Apple make that impossible?
Thanks @Tony! Glad to be back and I hope I can get to using odrive again- great tool!
