 ### Known Issues
 
+Builds made with PlatformIO are currently (v4.0) broken; the stream will die shortly after starting. See https://github.com/easytarget/esp32-cam-webserver/issues/218 for more info.
+
 The ESP32 itself is susceptible to the usual list of WiFi problems, not helped by having small antennas, older designs, congested airwaves and demanding users. The majority of disconnects, stutters and other comms problems are simply due to 'WiFi issues'. The AI-THINKER camera module & esp32 combination is quite susceptible to power supply problems affecting both WiFi conctivity and Video quality; short cabling and decent power supplies are your friend here; also well cooled cases and, if you have the time, decoupling capacitors on the power lines.
 
 A basic limitation of the sketch is that it can can only support one stream at a time. If you try to connect to a cam that is already streaming (or attempting to stream) you will get no response and, eventually, a timeout. The stream itself is a [MJPEG stream](https://en.wikipedia.org/wiki/Motion_JPEG), which relies on the client (the web browser) to hold the connection open and request each new frame in turn via javascript. This can cause errors when browsers run into Javascript or caching problem, fail to request new frames or refuse to close the connection.
