Welcome to the community, @fakhrizalakbar1! Could you kindly carry out the following steps to solve the issue:
- Create a new project from scratch/upload an xlsform as a new project
- Upload media under SETTINGS>Media
- Deploy if it’s a new project/redeploy if it’s an existing project
So this is the step moving forward because KoBoToolbox is now able to preview a form with media files before going live. So each time you add a media file, you should redeploy which is different then what it used to be previously (where you did not have to redeploy after adding a media file).
For details, please see the discussion that has happened in this post:
