The temporal.io page is producing an error that say contact customer support but does not provide a link for actually contacting support, nor does the site provide anything other than this forum as an option for support. It is very discouraging when attempt to use a product and the company hides features like this.
You can do it from https://support.temporal.io/

Hmm, the link just goes to a blank white page
Tried in a different browser and it went to Zendesk
