Ixpand drive not working with i0s 12

I recently update the software of my iphone 6 and ipad to ios 12 then suddenly the scandisk drive app is not detecting my ixpand mini. Thanks for any suggestion how to fix it.

i have iOS 12 and my iXpand works no problem so the issue is not likely related to iOS 12 itself. I would suggest to make sure you have the latest version of iXpand drive app. Then I would try power cycling the phone. if the ixpand still is not working test with some other iOS device to rule out any possible hardware issue with the iXpand and if it works on other iOS devices then I would try factory resetting the phone.
