Everything else

Start from what you are seeing rather than from what you think is broken. Each page below names the symptom, explains why it happens, and says what to do about it.

Several of these are the product working as designed, which is worth knowing before anybody raises a ticket.

#At a glance

Symptom	Usually because
Quality shows as a locked entry in the navbar and clicking it opens a marketing page	The Suite install is on the Standard edition. Quality is an Advanced-edition capability there.
Total issues looks higher than the number of problem pages	Each rule contributes its own page count, and the counts are not deduplicated. A page failing three rules adds three to the total.
Disallowed domain links rule and the search Domains filter always return zero in the standalone Capa	Both read the indexed list of outbound link domains, which only the Links capability populates. And Links is not bundled in the standalone app.
Rule is enabled but reports nothing at all	Disallowed macros, Disallowed labels and Disallowed domain links produce no query when their list is empty, and report zero rather than an error.
Blocked macro key catches macros from unrelated apps	Matching on the page byline, the search column and the search panel is loose. A key matches if either key contains the other, or if their final segments after the last "/" or ":" are equal.
Byline lozenge count and the panel's finding list disagree	The lozenge is recalculated from the page's current content on every render and counts only the eight indexed rules plus Disallowed macros. The panel reads the stored index and additionally
Issue was dismissed but the byline lozenge count did not change	The lozenge recalculates from the live page content and never reads the dismissal list.
Stale content and Disallowed labels always show as passing in the Page Quality panel opened from the	Both need the page's version date and label list, which are only supplied when the panel is opened from Capable Search results.
Clicking a slice of the "Issues by severity" donut does nothing	It navigates to Priority / Warning / Info section targets that no longer exist as sections. They are now plain navigation headings.
Pressing Refresh on the Dashboard spins and nothing happens	Queuing a run is admin-only, but the button is shown to everyone, and a non-admin's rejection is not surfaced on screen.
Two people looking at the same space see different numbers	Live per-rule counts, list badges and the Recent violations table are searched as the signed-in user, so they only include content that person can see. The weekly cross-space snapshots are c
Ordinary technical or product text is flagged as inappropriate language	The built-in list of roughly 300 terms is matched as whole words, and includes common words such as "crap", "damn", "anal", "cracker" and "hoe". The list cannot be edited or narrowed, and cu
Headings containing product names or people's names are flagged by Heading capitalization, and the f	The capitalization check is a simplified heuristic that does not recognise proper nouns.
You want a rule to keep running but stop showing up prominently	The single control both enables the rule and sets its severity. There is no separate "enabled but hidden" state.
