Camera and Network issue #11846
Description
Board
ESP32 CAM
Device Description
The camera live streaming and the network are not working properly after 3.3.x update.
Connected WiFi IP frequently show RTO, and live streaming is almost stopped.
Please fix it
It is working properly with 3.1.x versions
