Ring Protect Plus 30 day trial period question - moderators please respond

Dear moderators, I got two different answers from Ring phone support on this tonight. The situation is simple. I bought two Ring spotlight cams. One I activated 28 days ago (so had two days left on trial), and the other one today. Thinking that I would need Protect Plus for the first camera in order to maintain extended warranty, I bought the year Protect Plus plan from my linked Amazon account. Now, on the Ring account on my computer, it appears that BOTH cameras have a free Protect Plus trial period for 30 days meaning I will be getting 60 days on the first one, and therefore no need to launch the year protect plus plan that is ready to be activated. Is this correct? I noted there is a button to click on the Ring computer account to launch the purchased plan but was worried I would therefore lose this additional 30 days trial on the first camera, and the first 30 days on the second camera - or in other words, a month of free service. Can a moderator confirm that if you add a second camera while the first is still under the first 30 day free trial, they BOTH get 30 days now moving forward and therefore might as well wait to click on the year Protect Plus activation button on my account? And, Ring phone support should really have these answers to these simple questions! The second agent even said I would need to prove purchase of the Protect Plus purchase from Amazon with screen shots etc. when in fact it already shows it ready to launch in the Ring account on my computer. Also, now I don't see "x days remaining on trial" on the app. What happened to it??
