What is problem? (only list ONE problem per report)

The rumble doesn't work at all in game. When I press the home button I can feel 2 different rumbles pulses, but the rumble never works in game. I tried every mode in the web advance config (none, rumble, and memory), and also updated to the latest 24.04, did several factory resets, no change.
I looked up online and here, and couldn't find any info either.
I tested several games, it's the same on every one of them.
When I connect a real controller with rumble pack instead of the adapter, the rumble work instantly.

What did you expect to happen?

I expected the rumble to work once I enable it from the web UI and/or switched to rumble mode with the home button.

Are you using a real NSO from Nintendo or the 8bitdo mod kit?

A real NSO controller, connected to the 8BitMods blueretro adapter.

I also updated the controller just in case, and tested on the official NSO service, rumble works normally there.
When pushing the mode button, I also get the rumble pulses for the mode change (but no rumble in-game), so I don't think there is an issue with the controller.
It seems like it's either not recognized by the game or not triggering the rumble.

Did you enable rumble in the config?

Yes I did. I checked it several times. I was very careful and checked many times from your wiki if I was doing things the right way. Everything is set properly. It's just not receiving/triggering rumble.
Also did factory resets, upgraded/downgraded to no avail.
Is the rumble function tested as working on the official NSO controller with the lastest firmware(s)?
