Trial Subscription

[I-are-one]

   I purchased 3 “refurbished” Pro 4 cameras from Amazon.  I blundered through the setup process and, after many fits and starts, am about ready to move on to the mounting process.  However, only 1 of my 3 cameras is showing being enrolled(?) in the free trial subscription. I wonder why and I wonder if this is a present or future problem.  Any help - greatly appreciated.

Disregard my post. I see only one camera is eligible for the 3-month free trial.

Can you point me to where you found the information regarding only one camera is allowed on trial plan?
