The FAQ says that version 2019.4 is the minimum for running Unity Game Services Analytics. However, on the documentation page for the new analytics package (com.unity.services.analytics, https://docs.unity3d.com/Manual/com.unity.services.analytics.html), the supported Unity versions section of the page excludes a few versions after 2019.4, including 2021.x. Does this mean that Unity 2021.x versions are actually incompatible with Unity Game Services Analytics? Can I use com.unity.services.analytics in 2021.x somehow? Or can I use the Unity Game Services Analytics with the older analytics library, com.unity.analytics in Unity 2021.x? Or is it necessary to upgrade Unity to one of the supported versions?
