Spotlight solar cam gutter mount - ever available?

I have several spotlight solar cams that I am waiting to mount. There is a gutter mount that is advertised on the Ring website, but it is apparently never in stock - you can only type in your email to be notified when it is in stock. It has been several weeks, and no change in availability. Has this produced been discontinued? Will it ever be available? I can't find this mount on any website for purchase (I can only find the older model of the gutter mount, which does not look as sturdy, and is not specifically for the spotlight solar cams). Can anyone help?
