Grove OLED Display 0.96" 128x64 on Arduino Micro...not works

I really need to use an Grove OLED Display 0.96" 128x64 on my ARDUINO MICRO, but it’s not working. :confused:
The display works fine on the Arduino UNO.
Then I try to make it works with my Arduino Micro.
The correct pins for I2C communication should be:

2 (SDA)
3 (SCL)

as documentend here on the arduino micro offiacl page.
image attached.

No way, the display is not even turning on.

The Arduino Micro specs should be ok:
Operating Voltage 5V
DC Current per I/O Pin 40 mA

The Arduino sketches and library are I’m using are from seedstudio and they works fine on Arduino UNO, as said.

Please, someone could help me? I really tried to figure out what the problem is, am I ignoring something?

…of course I cant’t wait to make it works with the seedstudio Blended Micro!!!

It seems that the pin 2 (SDA) on my Micro is not working, I don’t have a multimeter here but I’ve tried with a LED…is not blinking on that pin.
I will check with another Micro board.
