After rendering a video in Videostew, you can upload it to YouTube with just one click. Typically, after you press the upload button, it uploads within a few minutes to YouTube Studio.

However, there might be issues with network conditions or account connectivity that can prevent a proper upload. In such cases, you can try to delete Videostew's access from Google account management and attempt the upload again. Please refer to the following steps.
Clicking the account icon in the upper right corner of the Chrome browser will take you to the Google account environment settings menu.

< Move to Google Account Management Menu >
Here, please select the "Data and Personal Information Protection" menu on the left side.

Scroll down to find the "Data of the Apps and Services in Use" menu, and here all services that have been granted access permissions are listed.

Find Videostew and select it. Then, by clicking on "Delete All Connections to Videostew," you can reset the account linkage.

Now, when you click the YouTube upload again, you can link a new YouTube account. Select the channel you want to upload to and upload the video! If it still doesn't work, there's a high chance it's a temporary network error.
