App review time

I submitted a simple app to Wix App Marketplace for review 8 days ago, still no response.
The app contains only one widget iframe and one control panel with couple options that are passed to iframe as URL parameters.
What is the normal review time? Will it take so long for each update to be approved?

Thanks

As per my experience the review time can vary anywhere from 1 day to a month. Really depends on the workload of the moderators and not the app size.
