Incompatible with Android 12 on some devices. As mentioned by several others (see reviews in February 2022), the app is reported as compatible and installs successfully but it immediately crashes after submission of login credentials. Even if the app would work to sign in, I feel discouraged by comments that suggest the app fails to connect to or control other Alexa-enabled devices. It seems to me that the latest app version requires serious testing by the quality engineering team!
