Can't add echo-speaks as a SmartApp

Hi all, I’ve followed the instructions accordingly and installed echo-speaks in the My SmartApps section of the (https://graph-eu01-euwest1.api.smartthings.com/ide/apps) IDE.

I then tried to do the same in the smartthings iOS app, after clicking onto Echo Speaks (main app), i got a popup saying Something went wrong. Please try to install the SmartApp again.

What could be the issue here?

It’s no longer allowed as of September 8th
