+Partially Signed Bitcoin Transaction Version 2 as described in BIP370 is not compatible with sending to silent payments as described in BIP352. In particular, the output script of a silent payment cannot be computed until after all transaction inputs have been added.
 Also, any inputs that the Signer has the private keys for must be signed with SIGHASH_ALL and all inputs must not have any scriptPubKeys with Segwit version > 1.
 Additionally, the silent payment outputs computed by a signer must be verifiable to other entities.
 Therefore, new fields and role responsibilities must be added to carry, compute, and verify the silent payment data.
