What does the alert message “This extension may not be supported” mean?

To restart iPhone 8 or earlier, press and hold the side button, then drag the power icon across the screen from left to right.

Wait for about 30 seconds, then restart your iPhone and try connecting the accessory again.
3. Clean the charging port
