For invoice templates that we have created in the past (prior to about 30 days ago), when the invoice template contains this placeholder text:

${Invoices.Invoice ID}

Then when we use this template and generate a Print Preview or convert our invoice to PDF we get the friendly Invoice ID that is displayed in the user interface. For example:

INV-123456

Now, for any new invoice template that we create, when the invoice template contains the exact same placeholder text:

${Invoices.Invoice ID}

Now when we use this template and generate a Print Preview or convert our invoice to PDF we get the internal ID of the invoice (the lookup value). For example:

714376000007204101

NOTE: This same issue is happening with Quote ID. For a previously created template, ${Quotes.Quote ID} displays the friendly value (e.g., QUO-123456). For a new template, it displays the internal quote ID.

Zoho, please comment on this. This is the second unannounced breaking change that you've made to quote/invoice templates in the past 3 months. This is unacceptable.
