Are you sure they weren’t just on the free CamPlus trial? You should be able to get them onto your Lite plan.
I did at first until it ended, I signed up for the CamPlus Lite for $0 after learning I could do so. The cameras began recoding again - for a small period of time - then reverted back to photos. Not only just photos, but that is when the Buy Cloud Recording ads began. You can check my account. One is a v3, one is the rechargeable outside cam, My wife has 3 v3’s, 2 are basically decoys at her fathers house. and 1 v3 is still in the box.
I and almost all posters here are just customers like you and can’t check your account.
