Tahoe Client
On macOS Tahoe 26 Developer Beta, BigBusiness Client can crash and needs upgrade.
This situation may resolve itself with newer Betas of macOS Tahoe so fingers crossed.
Landed Updating
Landed Updating shows you the newest landed costs on new transactions like Orders. Later when the order is converted to an Invoice the newest Landed Costs are included.
Once new Landed Costs are added in the new transaction they are saved for reference. The Landed Costs in the Order stay the same, while in the new Invoice they are new.
Saved Invoices show the Landed Cost that was updated when the invoice was created.
