Check that the reconciliation key is correct. It is the hashed/encrypted value of this field that is used to export and import audiences.
In case of hashing or encryption of the declared ID, check that the same parameters/encryption algorithms are used on your Website.
Only one encryption algorithm is supported: AES in CBC mode with a key size of 128, 192 or 256 bits, with PKCS padding.
Channel (Email/SMS/Other): This field allows to directly decrypt email addresses and SMS numbers. Make sure that the reconciliation key matches the setting of the Channel field. If you select "Other", this specific decryption will not happen and the reconciliation key will be used to reconcile the data.
It can occur that some data are missing when sharing an audience via People core service or when importing an audience. Only records of which the ID ('Visitor ID' or 'Declared ID') was able to be reconciled with the profile dimension are transferred. IDs from the People core service segments that are not recognized by Adobe Campaign are not imported.
