Physical keyboard issue

[S21user2021]

So, my question is about the physical (USB) keyboard which is not working anymore on Samsung phones. Previously I just had to plug the USB receiver to the OTG adapter and it worked flawlessly. Now, although the phone "sees" the physical keyboard in settings, it does not work at all.

Same results with S21 One UI 6 and S24 One UI 6.1.

If anyone has an info/solution... Tnx.

I've not used a USB connection with mine yet (I will try tomorrow) but via Bluetooth at least it works fine.
