_Include the following details (edit as applicable):_ - **Issue category** : Developer Tools - **Device type & OS version** : iOS - **Host machine & OS version** : Mac - **Issue Environment** : Unity Remote - **Xcode version** : 13.3 - **ARDK version** : 2.0 - **Unity version** : 2019.4.34 Description of the issue: Hi, Yuki here. I just downloaded the updated ARDK version 2.0 file, and I created a new Unity project. Once I imported the new ARDK file, the Unity console prompts these 2 errors: ![Screenshot 2022-05-27 at 3.13.07 PM](https://us1.discourse-cdn.com/niantic/original/1X/be268a6c18cf8e917ffec618fdaa7113a3abcc9c.jpeg) After that, I added the ‘Resources’ folder in the Assets, upon right-click to the create function, there isn’t any ARDK tab for me to add in the authentication file. I have also deleted the extra resources folder in the ARDK examples. Please help :") ---

Both lines use this operator: ??= Not sure, but i guess this is maybe a newer one, which is not supported by your C# or .NET version, because you are using Unity 2019.4. Is it an option for you to use a later Unity version? Else you could also maybe change the Projects settings/Player/Other Settings/Configuration part. These settings work for me (but it’s on Unity 2022.1) ![configuration](https://us1.discourse-cdn.com/niantic/original/1X/07421f538dd66c5e08d9ecda00da443de77e6bae.png) ---

Hello Yuki, I was able to reproduce your errors using Unity 2019.4.34. As @BBIT-Solutions suggested, you are seeing these errors because this version of Unity is [no longer officially supported by ARDK](https://community.nianticspatial.com/t/unity-2019-4-will-no-longer-be-officially-supported-in-1-3/1665). To resolve your issue, please use at least Unity 2020.3 when using ARDK. I tested with Unity 2020.32, 2021.32, and 2022.1 with no errors. You will also be able to right-click and see the ARDK tab to add your ArdkAuthConfig once you update to a newer Unity version. Please be sure to check our [Announcements](https://community.nianticspatial.com/c/announcements-about-the-lightship-developer-platform-covering-specific-technical-changes-and-advisories-such-as-feature-deprecations-bug-fixes-and-api-changes/8) page to keep up to date on ARDK releases and Unity compatibility. Thank you! ---
