Video Doorbell Pro Voltage status difference

Hello,Has anyone had this issue? Just noticed under the app's devices section, it shows "poor voltage" for the doorbell, however, when I select the doorbell and go to device health, it's telling me transformer voltage good. Are these two voltage statuses measuring different things (one voltage at the transformer and one at the doorbell)? I have the doorbell going to a transformer and that to an internal mechanical chime with the power kit battery. It's been wired this way for about 5 years now. Could the battery or transformer be going bad?
