Can't pair

[headshot2017]

After pressing the SYNC button on the wiimote and the LEDs start flashing, I tap "Nintendo RVL-CNT-01". It brings up the PIN input dialog for a second then closes right after, with the LEDs no longer blinking, and an error saying that the pairing failed.
A similar issue also happens when trying to pair through the device's Bluetooth settings page.

Samsung Galaxy A52, Android 12

The same for me, but I could connect after a lot of tries. As the app says, you must hold 1+2. I did that, keeping both pressed until I finished tapping 0000 on password and it worked. But all 4 leds is blinking and none of the buttons are working...
