Now it works! Simply update your IOS devices to SanDisk iXpand App Update to version 1.6.1 (newest release as of 3/14/2016) and now the Select + button works. After updating the app you may want to go into -> Settings ->iXpanD Sync and make sure both Contacts and Photos (allow access to…) and turned on (green).
Now I can select any photo from my collection of over 30,000 and copy the original to any folder on the iXpand drive that I want. Perfect!!! No more crashing!!!
BTW: You may have to wait a few second (depending on the size of your photos library) for the first screen of your photos to come up. With my 30,000 I wait around 30 seconds. You can view the entire library, or you can look at individual folders of your IOS photos library. Very nice.
Thanks SanDisk coders for getting this issue fixed!
