User Manual not up to date

I have just had installed two Ring Floodlight Cam Wired Plus devices and I added these to my version of the Ring App. (I already had an indoor camera and a Ring home security alarm system.) Not being very technically minded, I downloaded the User Manual for these cameras so that I could get instructions that would take me through, on a step by step basis, how to get all the settings that would be suitable for my use. But I found in various places in this Manual that the screenshots for some of the App screens were different from what I could see on my App. I went on to the online chat facility to be amazed to be told that the online manual is out of date and they don't know when it will be updated. Why would a Company update an App and not make the corresponding updates to the Manual? And how is a dinosaur like me supposed to get the best settings for my security devices? I am not happy!!!
