Ring Intercom

Hello i have a question. When i go to the doorbell notifications i can set up a popup notification and a vibration. Sadly at the lockscreen there is only the option "no notification". And beside the silent popup and vibration you dont have the possibility for a sound notificationLike most cellphone users the cellphone is on a lockscreen after a few minutes of inactivity. So i get NO notification when the lockscreen is on. Thats why i miss 90% of the doorbell notifications at my ring app.Is there a possibility (now or planned) to get noticitions even at the lockscreen?is there a possibility (now or planned) to set up a ringtone?
