Ring Wired - not enough power after App update

Hi all, I have a Ring Doorbell Wired which was working fine up to yesterday. My ring app on my phone updated (v5.45.0), and when I was viewing my video feed, the doorbell lost wifi connection. I tried to reset it up through the App, but it's saying my doorbell transformer doesn't supply enough power. Please see pic of my transformer attached.  Please help. Thanks. Ray
