RingCentral Subscription is not picking up on any activity of calls

Question

I'm running in Node.js.

My app is not picking up on any call action after successful subscription to /account/~/telephony/sessions

My Code:

    function setSubscription() {
    const platform = rcsdk.platform()
    platform.login({
        username: '+14706150273',
        extension: '101',
        password: '********'
    }).then(response => {
        const subscription = rcsdk.createSubscription().setEventFilters(['/account/~/telephony/sessions']);
        subscription.on(subscription.events.notification, function (msg) {
            console.log(msg);
        });
        subscription.register().then(function (response) {
            console.log(response.json());
            console.log('Success: Subscription is listening');
        }).catch(function (e) {
            console.log('Subscription Error: ' + e.message);
        });
    }).catch(e => {
        console.error(e)
    })
}

Console output after run showing successfully subscribed (but nothing after) - Calls are showing in the sandbox call log:

Success: Subscription is listening

For anyone that has this issue - make sure you have only 1 subscription of the same kind at a time. Multiple will create an issue.
