Late notifications

I’ve recently installed 2 sentry plus cameras at 2 locations. Both cameras have 128G sd cards. One camera is working great but the other is not. On one camera notifications come in about 1 hour after the actual event while the other’s notifications are almost instantaneous. At first I thought it might be wifi lag but I have two other devices both from different manufacturers and those notifications come on time. I have double checked and all settings for both cameras are identical. Any suggestions are greatly appreciated. I’ve attached a screenshot showing the event time and when the notification was received.
