Remote Event Receiver on Project Online Site

Hi All,

I am using a simple Provider-Hosted app containing Remote Event Receiver. The event receiver triggers when you create a sub site. It adds some lists on the newly created sub site.

I have deployed it to an Project Online Site Collection (PWA). When I create a sub site directly from the "create sub site" link it works. However when I use "Create a new project" link, it does not add my lists. It seem it doesn't work if you create a project by using "Create project" link. Any idea? I appreciate any kind of advice.

I appreciate any kind of advice.
Thank you
