Unfortunately my experience has been like Dave’s. There is no way to get support beyond the help pages and chat. I have NEVER seen phone support in a year on Shopify but I was able to click ‘contact’ and write support.
That option has not been available to me for some time now. If it’s a browser,cookie,cache problem I’d be happy to know. I did try with two different browsers on Windows and on two browsers on IPad.
To me it feels more like Shopify is controlling who has access to that or only chat, but I may be mistaken.
