Update Wednesday, November 1, 2017: version 7.1.2 of the MobileAsset app is available in the App Store, compatible with iOS 11+.
Update Monday, October 23: We are submitting the updated app to the Apple Store today. Approval usually takes 3-5 business days. If all goes well, it should be available by the end of the week.
Apple's recently-released iOS 11 requires that all apps are 64-bit. However, the current MobileAsset app (v7.1.1) is 32-bit, so it is not visible in iOS 11 and cannot be downloaded or run.
Wasp is working on a 64-bit version of the MobileAsset app and will release it to Apple's App Store as soon as possible. We hope to have this completed by October 22, 2017.
Customers who wish to continue using MobileAsset on iOS devices should not update to iOS 11 until the updated app has been released.
Customers who have already updated to iOS 11 but still need to run the 32-bit MobileAsset app may be able to downgrade back to iOS 10.3.3, following a procedure from Apple or other sources, found on the web.
