Help → Technical problem / bug. It is its own category so it reaches the right queue rather than sitting behind order questions.
The three details that matter
1. What you were doing, step by step. Not "bidding is broken" — "tapped the bid button on the item screen, the amount did not change, no message appeared."
2. What you expected and what happened instead. The gap between them is the bug.
3. A screenshot. Worth more than any description, and it carries the thing you did not think to mention.
Add your device and browser if you know them. A problem that happens on one browser and not another is already half-diagnosed. Which browsers does Metzee work in?
What makes a report unfixable
"It does not work." Nothing can be done with it.
No way to reproduce it. If it happened once and you cannot say when, say that too — but a bug nobody can trigger is a bug nobody can fix.
A screenshot of the whole screen with no indication of what is wrong.
Check these first
Half of what gets reported is one of these, and checking takes a minute:
An old browser. The commonest cause of live video failing. I can see the show but cannot hear it
A connection problem, which looks identical to a broken page. How fast does my internet need to be?
An in-app browser from a chat app, which is where video breaks for no visible reason.
None of that means do not report it. It means say what you already tried, so nobody asks you to try it again.
What is not a bug
A rule you disagree with. That is feedback, and it has its own category. Can I suggest something?
A problem with an order. Different route and faster. How to raise an issue
A wrong translation. Related but its own thing, and it needs the screen it appeared on. Reporting a wrong or awkward translation
Something in this blog being wrong. That is a bug and worth reporting — the blog is checked against the code, and a page that contradicts the app is a defect.
What to expect
You may not get a reply to every report. What you will see is the thing fixed in a later release. A bug affecting money or an order will be answered.
If it is urgent and about an order
Do not wait on the bug queue. Raise the order problem under its own category as well — the two are different queues and the order one has a clock on it.
