Sync erases cards on iOS

I do not have a normal workflow for studying, I just grab whichever device is more convenient at the time and create cards at random study the cards when I have a chance. So taking a preference for creating cards on one machine is not really an option for me.

I have been using both the iOS version on the iPad and the Mac version to create cards. The problem is when I sync with the Mac. If I create cards on the Mac, they sync with the iPad, but when I create cards on the iPad, they don't always sync with the Mac. Especially if I create cards on both before I sync or make alterations to cards on the iPad that were created on the Mac. It seems as though the two-way sync is not so two-way with the Mac having the preference. I currently have all three checkboxes checked in the options menu for syncing but I'm not sure what the right combination really is. I want things to sync both ways and not lose cards unless they are deleted by me.

If you could provide some assistance, or maybe a step-by-step of how to set up the preferences in both apps to make real two-way sync possible, I would greatly appreciate it.

    I think sync should work fine if you check the box that says to copy back new cards created on the touch device.
    Are you sure the notes are disappearing?
    You can't sync one device with two macs. The way our syncing is setup, this will cause problems.
    Kind regards,

    I'm not sure they are disappearing. I just can't find them anywhere on either device. I have been syncing with multiple macs, but I have been copying the App Support file from one Mac to the other after syncing the iPad. Could this be causing the problem?

    I have all the boxes checked in the sync window.

    How exactly does the sync "handshake" work? ...all new cards are copied to the Mac and then the whole database is transferred. What happens when card are deleted or moved on either end? Maybe if I had a better understanding of the sync process, I could try to prevent the problem myself without bothering you guys.

    Thanks for the extremely quick response.

    Hi Brandon,

    Basically, the iPad keeps track of which notes and cases are new or have been updated since the last sync with any Mac. When the next sync happens, whichever Mac that is, it will send back the new notes and cases, and updates. As long as the Mac can find the updated notes and cases, it should work. The Mac then sends back all of the new stuff, replacing everything on the iOS device.

    So, to be honest, I think what you are doing should work. I'm not sure why it wouldn't.

    Might be worth backing up your data, and then doing a few tests, creating a few new cards, and updating some, and then syncing with different Macs to see if it is OK.
