Video captured, but no email sent

[carbonita_23339214035]

Has anyone seen issues with email NOT being sent, even though video IS captured via PC client and on camera-local storage? This occurred with all of the 9 Reolink RLC-{410s,411ws} and C1's for a 20-minute period of time today. The cams use smtp gmail, and have worked properly prior to, and subsequent to, this anomalous period. The email interval time is set to be shorter than the interval of motion events. The cam networks were connected to the internet, since another brand of cloud-recording cam was operating.
