can't change address on SparkFun Qwiic Single Relay

Qwiic System
1

I tried using example 6 from the SparkFun_Qwiic_Relay.h library.

to change the address from the default 0x18 to a new value (e.g., 0x09);

The code reports that the address has been changed in the serial monitor

But when I run a I2C after, its still the 0x18.

I tried both an ESP32 and a Arduino, no luck.

Thanks,

I ended up using the example from this old hookup guide - it worked
