Adafruit library for MCP23017 is Not working using new Arduino Nano ESP32 development board (Arduino IDE).
Arduino Nano ESP32 development board is using ESP32-S3 MCU.
When compiling using ESP32-S3 board, there was no error but when using new Arduino Nano ESP32 board, there were errors.
Can somebody please update the library? Thank you in advance for your help.
Have you tried looking for a compatible library? There are a lot of different Arduinos and they are open sourced. That allows anybody to make them. Each processor uses different machine code internally and has different hardware configurations. It takes time for the volunteers etc to actually write the library and publish it. Generally it is done for the love of it and on compensation for it. From what I see every time a new processor is put in an Arduino package the software control its features will be lacking. Feel free to write that library. They concentrate on making the basics like the compiler work first so it can be sold.
No someone here can't do that.
That library is the intellectual propriety of Adafruit. If you want a change to it then go over to the Adafruit forum and ask how you can put in a request to add this feature into the existing library. There will be some GitHub repository somewhere where you can make a feature request.

Thank you!
Here are the compilation results using ESP32 S3 Dev Module and Arduino nano ESP32 as board. I used the example code Adafruit MCP23017 Arduino Library (mcp23xxx)blink).
ESP32 S3 Dev Module as board: (compilation OK)
Sketch uses 287321 bytes (21%) of program storage space. Maximum is 1310720 bytes.
Global variables use 20304 bytes (6%) of dynamic memory, leaving 307376 bytes for local variables. Maximum is 327680 bytes.

Error compiling for board Arduino Nano ESP32.
I tried the IDE Tools option "Pin numbering: By GPIO number (legacy)" and the compilation was OK!
I will try if the example code will work when i upload it to the new Arduino Nano ESP32 board.
Thank you!
I'm glad you got there by yourself, it's always a great way to learn something new as it will stick 
When I saw this I immediately thought it would be the culprit.
Congratulations, enjoy your Nano ESP32 (I love this board)
