Unable to create Adobe Embed API project

Hi,

We are looking to utilise the Adobe Embed API, unfortunately we have many domains so I have taken up the task of creating a new project for each domain. I have so far created 20 projects with Adobe Embed API credentials for each.

I have just attempted to add the 21st project and corresponding allowed domain but I get the spinner to save and then the field is emptied, with no error. I'm therefore unable to proceed.

Any thoughts on cause? I wonder if there is a maximum number of projects for each product type?

Thanks

T
