Hello!
The certification process for a product in the Windows Store typically completes within a few hours. However, it can sometimes take up to three business days.
If your app has been pending for about two days, it’s still within the normal time frame.
If it exceeds three business days, you might need to check the app certification process for any updates or notifications regarding potential issues that could be causing delays.
