We are migrating from Azure Media Service that does not have this problem.

We have a use case where we support users in chrome recording and uploading video.  Chrome only offers webm support.  We were hoping to use the video encoding solution to standardize all the uploads into MP4.  But what we have found is if we submit a job with a webm file type it just gets stuck in the  queued state and has no update.

I have heard mixed responses about webm support (sales says yes, technical team says no).  Has anyone had success with webm?
