AMS RFID not working anymore

The RFID board for slots 3&4 have suddenly stopped recognising filaments. Restarting the AMS is not working and I cannot seem to find a replacement RFID board on the store. Is there any solution on that?

Check internal cable connection, otherwise contact Bambu Lab support.

Already checked it and it seems to be ok! Support it is I think!

Did anyone report that bug so then may be fix buy a firmware update. I look in the bug and firmware channel there is nothing so far.
