We are aware of the following known issues with Unity 2019.1. They are not seen with Unity 2018.3, so for now we recommend to stick to that version.
- App fails to resume on some Android devices after confirming the camera permission dialog. This is seen on many Android devices, but not all. Pause-resuming the app will continue it, the app will also load fine on the second run if the permission has been granted before. A workaround exists:
- Enable "Delayed Initialization" in the Vuforia configuration
- Disable the VuforiaBehaviour component on the ARCamera in your first AR scene
- Add the attached RequestPermissionScript.cs to your ARCamera. This script will request the Camera permission using Unity's own APIs and initialize Vuforia only after the permission has been granted.
- In some cases, Vuforia scenes take longer too load on iOS than expected. This is not seen consistently. Investigation on the root cause for this issue is still ongoing.
- Update: this has been fixed in Unity 2019.1.4f1
