Disclaimer: I am currently a customer who had financial loss because of them.
I'm sorry that you had this experience with imgix. We have had challenges in correctly addressing support issues during this period -- support has been swamped. We've expanded that team, and we're continuing to do so.
You're right, we didn't tweet this blog post, but we did e-mail it to all customers with activity since Jan 1 2017.
In this case, we didn't properly convey that the Shopify integration guide we provided wasn't an official integration with Shopify. It was meant as a best effort "here's how you can do it" sort of thing. I requested that we take it down because it wasn't working due to a change on the Shopify side which prevented us from purging images.
I'd love to talk with you directly to try to make this right for you. If you'd like, my e-mail is in my profile.
"Support is on-call during regular business hours, Monday - Friday, and premium customers can request SLAs for support."
This, while other users complained to me via twitter/email that they were also not getting any valid responses. I would not send those words while my service is not working as expected.
I'm in the process of moving out of Imgix esp. after your support said they would be happy to cancel my account if thats what I wanted.
The pushback from your support made me setup a production level thumbor instance which will go live next week.
Thanks for your reply but I wish you had replied to https://twitter.com/troysk704/status/841158793287278593 sooner.
Best of luck with your new solution.
Their support (after few days said), they don't support Shopify. Their whole pitch was; we are Shopify compatible; when we signed up.
