Fix available for Iphone X and iOS 11.1.2:
To All... I was having the same problem using a 256GB iXpand USB 3.0 Drive. I bought it a week ago. It worked with my Ipad Pro but did not work with my Iphone X (both using iOS 11.1.2). The ipad pro could transfer files from both the drive and the ipad. My Iphone X would recognize the drive and would read files from the drive but I'd get the same error everyone else was getting when I tried to transfer files from the phone to the drive. I had the following setup: App version 4.4.6. iXpand Drive SDK v107_223. Drive Firmware ver 184.108.40.206. File System exFat. The card type is 3.
Sandisk pushed an update to the App on Tuesday on the Apple App Store. After the update, I now have App version 4.5. iXpand Drive SDK v107_223. Drive firmware version 220.127.116.11. File system exFat. Card Type 3. After the update the drive works fine with my iPhone X (was able to transfer files from the iPhone X to the card and I can use it directly with the camera), Ipad Pro, and my PC.
Note, it still is card type 3. I do believe it is a firmware problem since it now works for me. Give the update a try before you send back your drives via RMA.

By any chance you know the difference between type 2 and 3 cards? Is type 3 supposed to be faster? If Sandisk has fixed it through software and firmware like creese mentinoned, then I'd love to get the type 3 card version instead for better performance.
For the record, the iXpand Updater provided by Sandisk isn't showing any new firmware version even though it seems like creese has a newer version 18.104.22.168.

That's great to know. I'm still trying to find out the difference between type 2 and 3 cards, but for some reason I still couldn't find any information on type 3 card.
