The delays for iOS were stated as being for the following reasons:

The Company awaits Apple’s verification and authorisation to release the Xped App on the
Apple App Store. This release can take between 2 to 5 weeks depending on Apple’s backlog of
processing and verification which is unusually long due in part to the new iOS 10 release and the
fact that the Xped App needs to be tested against hardware (IoT Gateway) which requires Xped
to provide evidence via a video that the software works correctly.

Regarding the on-boarding for iPhone users, according to the ADRC user guide:

For iPhone users, the user activates on-boarding mode by selecting a menu item in DeB before
tapping on the Thing.
