Warning!
Google has announced that support for Universal Analytics will end on July 1, 2023. They recommend using Google Analytics 4 instead.
This asset does not have support for Google Analytics 4, at least not yet. We haven't yet made a final decision on that. It is possible that we create a different asset with an upgrade path from this asset.
So, for now, if you purchase this asset, please understand that this particular asset may stop working on July 1, 2023. Because of this, the price has been reduced.

Supports Unity 2022 and beyond.
Also tested with Unity 2021, 2020, 2019, 2018, 2017 and 5.6.
