AP not receiving input from TX

FC: Matek F405 TE
RX: Matek R24-D
TX: iFlight 2.4 GHz

Board can connect to AP via WiFi and USB. As far as I can tell TX and RX are on same ELRS firmware and bound. I’ve tried all serial ports on the board, checked continuity, cannot get inputs on ardupilot from the TX. Offering a reward for whoever can help me resolve :blush:.
