The Ground Plane sample app does not allow re-positioning of the annotations into a new area after pause and resume. VISLAM may fail on environments with predominantly edgy structures with fine lines w/o other texture. Using multiple trackables simultaneously while Extended Tracking them on Vuforia Sensor Fusion provider may lead in edge-cases to degraded tracking quality. In cases where applicable, it may be necessary to go back to a target and redetect it if extended tracking does not resume normally. 
This can be mitigated by encouraging users to move the device around a bit to reinitialize tracking after resuming the AR session.
PositionalDeviceTracker may show some tracking instability after pausing and resuming the application when VISLAM Fusion Provider is used. will return false, even when the call succeeds. The device tracker static mode needs to be configured before target trackables are activated for extended tracking to work. We recommend using ADAPTIVE if robust tracking during very fast motions is required. Model Targets may switch to EXTENDED_TRACKED more often during very fast user motion when the motion hint is set to STATIC. Model Targets with motion hint STATIC are more sensitive to wrongly specified physical size in the dataset. Deactivating/activating the Model Target improves the situation - but user will have to start experience again with detecting the Model Target. Device Tracker reset during Extended Tracking with Model Targets might in some cases lead to unexpected relocalization issues. The native Model Targets GuideView interface still uses the legacy y-down camera coordinate system convention in the getPose/setPose methods. See the Unity Migration Guide for details and workaround. #INSTALL GOOGLE ASSISTANT N910A GENERATOR#
Area Targets created prior to 9.7 or created with the Area Target Generator of earlier versions will not work out of the box with the Occlusion Mesh and Mesh Collider settings in Unity. Playback of recordings from the Session Recorder do not support Ground Plane experiences. 
Fixed an issue that caused the Vuforia Engine SDK to show unexpected behavior in very rare situations upon start. The equivalent of this page or topic can be found here: Vuforia Engine Release Notes. We recommend migrating to the Vuforia Engine 10 API before this page is removed in February 2022. It has been deprecated and will no longer be actively updated. This page concerns the Vuforia Engine API version 9.8 and earlier.
