DIAGNOSIS This is a storage or subscription issue. Either the microSD card is full/faulty, or you don't have a Cam Plus Lite/License for event recording.
FIX First, check your subscription in the app. Go to Account > Wyze Services. If you have Cam Plus Lite, ensure it's assigned to the camera. For SD card recording, go to the camera's settings, tap on Advanced Settings, and select Format to fix card errors.
IF THAT DIDN'T WORK The SD card might be dead. Try a different, high-endurance card (Class 10, 32GB recommended). Also, ensure Event Recording is toggled ON in Alert Settings.
HEADS UP Without a paid subscription (or the free Cam Plus Lite), you only get a 12-second cooldown between 5-minute event recordings, which feels like it's not working.
