TimL,

I just got off phone with some "advanced" support through sales.  If they were correct, it is quite possible that the notice sent out is really trying to say that the old shipping module will become unusable if you are using the 2022 or older version of QBDT as Intuit is migrating to the new Ship Manager based on ShipEngine targeting a 31-May-2025 release date.

After 31-May-2025, you will not be able to use old shipping module/method in the 2022 and older versions of QBDT.  But if you are using or have upgraded to any 2024 QBDT version, the old ship module will continue to work after 31-May.

Intuit does plan to release new Ship Manager targeting 31-May, but they seem to be running late.  It will become available via the usual update process once it is released.  You probably cannot use the old ship module/method in 2024 QBDT once the new Ship Manager is released and installed through the normal update process.
