This is weird, the first time I build the project it was working perfectly, but after that every time I build and try to run the app I get the following message: "This device has failed to start the Positional Device Tracker. Please check the list of supported Ground Plane devices on our site: ..."
The build that has worked was made with Unity 2017.3.1f and Vuforia 7.0 after the second build it stopped working, so I went to the device list I noticed that my device need Unity 2018.1 + Vuforia 7.1, but even after upgrading Unity and Vuforia I got the same error.
Device: Xiaomi Redmi Note 4 (Snapdragon) Android 7.0 (MIUI 9.5)
Ground Plane (7.1.30)
I know the device support ground planes because the first build was working without any problem, how can I make it work again?
