PDF Invoices not attached

Good day
Invoices are no longer being sent out as an attached PDF but appear in the body of the e-mail message.
The legacy features option is no longer available under settings to select the Internal PDF generator.
Please advise how to set invoice as an attached PDF now.
Thank you

As the Forum’s FAQ/Rules require you to do, you should have searched the forum prior to starting a new topic. This subject has been discussed several times lately. The Internal PDF generator is available under Obsolete Features.

Thanks.
