You will need to render your scribe from the desktop version of VideoScribe. You still need to pay for rendering on the mobile version of Tawe even if you have a subscription.
You can save the project to your online directory from your mobile and this will allow you to access it and publish it from your desktop.
I'm a pro user and have a videoscribe yearly subscription. Why am I no longer able to publish my video on Tawe? and why is it asking for credit? I use to be able to do this without credit or paying for the service.
