When I upgraded from 1P 3.8 to 3.9 on my OsX machines i inadvertently produced a problem because the dropbox folder wasn't in the default location on one machine. that meant one machine was synching to dropbox and the other to iCloud or something else (who knows.) I discovered the problem when I changed the login to a website on one machine and the change didn't show up on the other.
I fixed that problem by using the dropbox ap to move the folder back to the default location.
But when i asked 1P to start using dropbox on that machine it happily created a 1p folder in dropbox and put its keychain there, ignoring the 1pkeychain in the dropbox root directory. That meant there were 2 1P keychains in dropbox - one in the root folder, the other in the 1P folder. I didn't think that would work.
I think I fixed that by turning dropbox on and off on the other machine causing it to use the keychain in the 1P folder (and also creating a backup keychain in that folder.)
Now the challenge - how to get the iOS devices (iPhone and IPad) to synch with the proper keychain on dropbox.
Does turning dropbox synch on and off on the iOs device point it to the proper keychain, and how can I be sure?
I understand this is all in the name of sandboxing and security, but a roadmap would have been helpful. I hope I am not walking into quicksand here.
