Shown here: move-in → sign the lease via email → check the PDF file under Tenant > Documents, Tenant > Communications, and the email received by the tenant.

Reported by: Sarah M.
The PDF under Tenant > Documents correctly shows the tenant's signature.
However, the PDFs attached to the Welcome Email / 'Move-In Completion (Lease Available)' trigger and the file under Tenant > Communications still display {{sig}} as a placeholder.
