Start both video and ringtone automatically on X933

Ok, clearing cache also worked. Thanks!
Last question:

How do I configure the relay so that the unlock button on the received call works?

Thanks. The article says that I have to add my indoor monitor to the "Access Whitelist > Contact Setting". Where do I find that on the X915S?

Thanks. I just did that. Now I have two monitors in my display (same as in the picture). Isn't it possible to have just one monitor which can open the door? Now I have one standard one and one "gate" which I have to choose from?
