Now that the plugin & server changes are merged and server changes deployed, feel free to test the Android changes by creating orders using IPP and POS in the JN store using secret store with ID 12613 (no shorthand for this). The channel should show In-Person (POS) for POS transactions in wp-admin > Payments > Transactions. Alternatively, you can use Jetpack beta for the WooPayments plugin and use a branch that has the latest develop commit from Dec 5.
