When uploading a video thumbnail for the experience where I’m hired as a developer, the website shows “Unknown Error, please try again later.” Despiste the failure, 500 Robux is charged on every attempt, and no records appear on the My Transactions page.
Steps to reproduce:
- Go to Creator Dashboard > Experiences > [Select Experience] > Thumbnails.
- Choose Video Thumbnail and paste a YouTube video link.
- Click Submit (the UI indicates a 500 Robux fee)
- Error message appears.
Result: 500 Robux is charged for each attempt

My Transaction page right after the bug:
Expected behavior
The video thumbnail should upload successfully or the submission should be blocked with a clear, actionable error without charging Robux.
If a charge occurs, a transaction record should appear in My Transactions page.
