After video playback of events stopped, I signed up for (and paid for a
year of) an Aware subscription, yet the events being captured only
display a single image, not a video clip. I have the wired doorbell
camera and video used to playback.
Thank you all. Issue resolved. Nest Aware subscription renewal
apparently “was not completed because of a system error.” I redid the
Nest Aware renewal and all is fine now. Thank you for the help.
