I am not getting any lights on since I updated to 0.13.0-b6 from b5. I removed the ESP32 from my QuinLED and connected to PC and used WLED installer v2 to make the upgrade. Plugging the ESP32 back in, no lights. I tried taking another ESP32 from another QuinLED running non-beta WLED and the lights turn on. I confirmed pins are in tight so I don’t think its a connection issue. I ensured the LED set up is set up to my SK6812 lights. Any idea what I am doing wrong??

Check out PIN number for LED. If it changed set proper PIN number
