Bug: Can't upload new app - One of the submitted files doesn't have the right media type

I've been unable to upload a new app to Garmin IQ app store for about a week now. I can get past the first step where .iq file is validated. Then I enter description, what's new, cover images and populate other mandatory fields, and I get the following error when I attempt to submit:

{

  "status": 415,

  "message": "HttpClientErrorException while adding app. One of the submitted files doesn't have the right media type"

}

I have checked to make sure all image files I'm trying to attach are either JPG or PNG and all are under the maximum specified sizes.
