Review changes is the page between the grid and your store. Nothing is written until you press Apply there.
Getting there
The grid's primary button, Review N changes, opens it. It is off while you have no draft changes, and it waits for any edit still being saved.
What it lists
Every draft change of this kind of row, 50 a page, each with:
- the row and the field,
- In your store now, read from your store at that moment,
- After you apply,
- Remove, to drop that one draft.
A draft that clears a value says so: "No value. The 12 cm is removed."
Under the banner the page says what applying will use of your month's values. See Plans and the monthly limit.
Drafts on other kinds of row
Review changes on Products names drafts waiting on Variants or Orders, with a link to each grid. Each kind of row is applied on its own.
Discard all changes
Asks first, then drops every draft of this kind of row, on every page. Nothing in your store changes.
Apply
Apply N changes sends only the cells you changed. The first time, Shopify asks in its own window whether the app may edit your store. If you refuse, the page says "Nothing was updated" and offers Allow editing variants. If you allow, the page moves to the result. See What happens when you apply.
