Getting help and submitting a ticket
Reach the team when something is not right.
If you hit a problem or have a question, open a support ticket from the site. Describe what happened and submit; you will get a reference and can reply to keep the conversation going in one thread. The team sees your ticket and can respond and update its status.
For catalog problems specifically, the fastest fixes are often self-serve: report a broken link, edit an entry, or complete missing data.
