Qwiic connector not working

The Pico LTE has 2 Qwiic connectors. I can only get one working (the one closest to the neopixel/corner), testing with two different sensors. I tried adding 4.7k Ohm pull up resistors to my circuit, still not working. Am I missing something? Also, are pull up resistors necessary?

Also, are the docs correct that both Qwiic ports are connected to GP12 and GP13 on the Pico? If that’s not the case, that might be what’s wrong.
