Have you set only one set of pull-ups active on the bus, like last time? Using SparkFun Qwiic Multiport and Qwiic Components in Series
Share a photo of your setup. Test the qwiic micro with a basic blink sketch to confirm it is working properly alone…then add the 1st qwiic device/sensor (whichever one you’re planning on keeping on the bus permanently, that one should be the set of i2c resistors that you leave active)
