1. Issue 1241180 (which makes Unity on iOS to not process any Input from controllers) may make this impossible to test in some versions
2. 1241180 is Introduced in 2020.1.0a17 and fixed in 2020.2.0a12, it was backported to 2019.3, 2018.4 streams
3. I tested the first versions of streams 2018.4, 2019.3 to verify that the issue was in these streams, however backports with 1241180 make the issue impossible to test it in later versions of these streams
