Known issues

Scenes containing the infrared viewer render incorrectly on Android build targets and in scriptable render pipelines such as URP and HDRP.
Use of the LeapCSharp Config class is unavailable with v5.X tracking service
Repeatedly opening scenes can cause memory use increase
Currently the Ultraleap Hand Tracking feature for OpenXR requires the New and Legacy input systems to be enabled, to simultaneously use OpenXR and the Ultraleap Unity Plugin's features.
The OpenXR Leap Provider does not currently support the Confidence hand property (and will return fixed values)
If using OpenXR when using Unity 2020 and Ultraleap Tracking Plugin via .unitypackage, an error will appear on import relating to HandTrackingFeature. This has been fixed by Unity on Unity 2021
- A workaround is to right click on \ThirdParty\Ultraleap\Tracking\OpenXR\Runtime\Scripts\HandTrackingFeature.cs and select 'Reimport'

After using Ultraleap OpenXR in Unity Editor, the tracking mode of device 0 will be set to HMD until the Unity Editor session ends. This can stop the testing of non-XR scenes until the Unity Editor is re-opened
