Razer Kishi 2 for Android is Incompatible with CODM even though Nexus Lists It

I bought a Razer Kishi 2 controller to play Call of Duty Mobile (CODM) on my Samsung Galaxy S20 mobile phone. The Nexus application lists CODM as being supported. Besides - why would it not be supported? Surprised to find out that the Kishi 2 does NOT work for CODM on Android phones. There’s a work around if you have a Bluetooth controller lying around that’s always turned on, or if you use a 3rd party application - but that risks being banned for 10 years. I’m seriously disappointed and will be returning the Kishi 2.
