upgrade to featured email won't send if plan is paid-plan

[Wei Hong]

Dear Flynax Dev.,

When upgrade a listing to featured using free upgrade plan, users receive notification email telling that their listing is featured (email template key: listing_upgraded_to_featured), in the email include price which is obviously Free.
But when users upgrade using a paid plan. They only get the Invoice email (email template key: payment_accepted), there is no (email template key: listing_upgraded_to_featured) sent to them.
Is this intended? If so how can I make the email (email template key: listing_upgraded_to_featured) sent to user who use paid plan as well? As of now, it only sent if user use free plan.

Thank you

Edited: I just looked at the email template and see
{if paid}
That means it should send to paid plan as well. So this is a bug I assume? Would flynax take a look at it?
