@BarkingDog Thanks for getting back to me! My apologizes, as I thought my team had updated it sooner. If you go back to the first link your referenced, it should now have a clickable link to download the manual. You can get directly to that manual also by going here. Let me know if you have any other questions on that! 
In regards to support; if your Ring device is not functioning/working/poor performance, you will reach out to Ring support via phone for more troubleshooting and help. If you have pre-purchase questions, how it works with a Verizon bill/account, where to purchase, and such like that, you will contact Verizon.
In the event you need to contact Ring support, I recommend calling in directly, as this is a neighbor to neighbor support forum and not a direct line to support. Please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19. This has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
