Just for clarification, Updating OpenTx is not updating the IXJT. The internal module needs a separate update. It will make the radio compatible to the new receivers.
I suspect you are dealing with the bad packet pass though. ACCST v1 vs v2 incompatibility issues.
Please tell us exactly what FW you have uploaded to the TX and RX. We will need the actually nomenclature.
The Tx was shipped with ACCST v.1.x.x x And the new RXs are shipped with the much safer v.2.1.xx.
