Update - 6/24/19 - The Wixie app has been updated and this new version includes a fix for this issue.
In late October, Apple released iOS 12.1. This updated OS introduced an issue on iPads using device management software, such as AirWatch or JAMF, that prevents Wixie from accessing the camera and microphone.
iPads running iOS 12.1 that do not use MDM software are able to access the camera and microphone without any problem.
While we did not create the problem, we realize our users on iOS are greatly affected and need us to resolve it.
Please know that we are working diligently to see if we can provide a solution to this issue introduced with the iOS 12.1 update.
