I have the 2020.3.32f1 version of Unity and have tried to open Mapbox version 2.1.1 - the current one I am being told by the Mapbox website to download. It says I need Unity 2017 and higher so everything should be right, correct? Then why does it not load properly and I get the following errors:
Assets\GoogleARCore\SDK\Scripts\ARCoreBackgroundRenderer.cs(43,17): error CS0246: The type or namespace name 'ARBackgroundRenderer' could not be found (are you missing a using directive or an assembly reference?)
Assets\GoogleARCore\SDK\InstantPreview\Scripts\InstantPreviewManager.cs(32,23): error CS0234: The type or namespace name 'SpatialTracking' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)
Assets\UnityARInterface\ARRemote\Scripts\ARRemoteEditorInterface.cs(40,17): error CS0246: The type or namespace name 'ARBackgroundRenderer' could not be found (are you missing a using directive or an assembly reference?)

A polygon of Mesh 'cone' in Assets/Mapbox/Examples/2_AstronautGame/AstronautGame/Park/cone.FBX is self-intersecting and has been discarded.
Problem detected while importing the Prefab file: 'Assets/MapboxAR/Prefabs/AR.prefab'. The file might be corrupt or have missing nested Prefabs. See details below. Warnings: Component at index 2 could not be loaded when loading game object 'ARCamera'. Removing it.
So yeah, no matter what I do, it won't load/open properly - the examples window from Mapbox doesn't open, nor does the Ampbox tab appear at the top of the Unity UI. It's really, really annoying, I can't even open the thing!!! I just need to get into it so I can start learning with the PocketDroid Go example if anyone knows that one... Please help it's been days and I am getting nowhere and it's literally step one: "open the package!" :(
Problem solved - Unity changed the name of ARBackgroundRenderer to ARCamera in like 2019 or something but Mapbox have never updated their SDK, hence the errors. If you use the April 2018 version of Unity, it works.
