Hi @tdejoigny-ledger

Thank you for raising this issue. From what I saw, the current behaviour is:

• If Contract Data is enabled, alert the user if there is data in any clause of the tx; otherwise, reject any tx with data in the clauses.

Can you clarify what is the expected behaviour between:

1. The user should always be able to clear-sign, even if there is data in at least one clause of the TX.
2. The user should always be able to clear-sign, and if contract data is disabled, then from the ledger live, we should not add data to the clauses of the TX.

If the expected behaviour is 1, then I can easily change the setting in app-vechain to:

• If Contract Data is enabled, alert the user if there is any data in a transaction; otherwise, do not alert the user and clear-sign.

If the expected behaviour is 2, then we should change the ledger live vechain implementation to:

• Retrieve the setting before sending any TX and avoid adding data to a TX if contract data is disabled.
