When importing invoices to QBOnline, why is the default custom template not used now?

This used to work up to 12 July 2025, but since 19 July 2025 any imported invoices use the QB standard template, which doesn't include our necessary information.

The workaround seems to be to manually change the design of each imported invoice to use the custom template. But this is totally impractical if there are many invoices.
