I recently received my Adafruit STEMMA Soil Sensor and followed the instructions here: Overview | Adafruit STEMMA Soil Sensor - I2C Capacitive Moisture Sensor | Adafruit Learning System
When I run the example code with my Arduino Uno, the serial monitor only prints “ERROR! seesaw not found”. I have checked the pin connections and used an i2c scanning sketch, which couldn’t find the device. I know the Arduino works with other i2c devices. I’ve also tried both 3.3V and 5V supply voltage.

From other sites, it looks like this is a common issue with this sensor. Are there any suggested fixes or should I request a replacement?
Thanks in advance!
