In version 4.3 of the EVA App, we are introducing an important update that affects EVA 3 Plus devices. These devices are transitioning to our own mobile device management system, Liger MDM, through a guided, step-by-step process within the EVA App.
If the migration fails before the installation is complete, a manual factory reset will be required.
