Camera all of a sudden quit recording

Hey all,

I have a Xfinity camera  (Forgot the model number but its the one just before the newset one...  Its white, but does not have the ability to talk through it).  Anyhow, a couple of days ago, it just quit displaying motions and recording.   The camera DOES work.  I am able to connect to it, I can view live video, etc.  It is NOT a connection issue.  My 3 other camera that do 24/7 recording work fine.   I do have a tech coming on Sat to fix/replace, but I would love to figure it out myself to save the time on Sat to do other things.  I have tried the following:

Reset the camera

test Outlet it is plugged into-- It is direct connected into outlet.

Reboot Touchscreen, security router, modem, and my personal router,

Turned recording off/then back on in the App.

Attempted to record manually....  camera showed as recording, however, the clip did not populate on the app.  

There was NO power outages prior to this issue occurring.

It just seem the cam lost its ability to record  There are NO error messages and the "REC" image is present.

I have already reset equipment multiple times,

My interent connection is good.  Gigabit Download/ 40mb upload

Any ideas?   Luckily, the cam is under warranty.    I just did notwant to spend my Sat with this if possible.
