Troubleshooting Canvas Design Studio

The issues merchants actually hit, roughly in order of frequency — with fixes.

The "Design your own" button isn't showing#

• Confirm the Design Studio block is added to the product page template in the theme editor and the template is published.
• Check the product actually has a template bound to it (Products page in the app). No template, no button.
• If you enabled "Hide 'Design your own' button", that's working as intended — the theme's Add-to-Cart button is now the entry point.

Inline mode isn't replacing the gallery image#

Inline mode auto-detects your theme's gallery element, and most themes work out of the box. For unusual themes:

Fix: set the Gallery selector override in the block settings to a CSS selector matching your theme's main product image container. Your theme developer (or a quick inspect-element) can identify it in seconds.

Background removal is slow the first time#

Expected. The AI model runs entirely in the customer's browser and downloads on first use — after that it's cached and takes seconds. If it's disabled entirely, check your plan: background removal needs Starter or above, with monthly allowances per plan (see Plans & Billing).

"Template limit reached" when saving#

Published template counts are plan-gated: Free 1 · Starter 5 · Growth/Scale unlimited. Delete an unused template or upgrade. Adopted starter templates count toward the limit too.

There's a watermark on the design preview#

That's the Free plan's "Powered by Design Studio" mark on the cart preview only — production files are never watermarked. Any paid plan removes it.

No PDF / SVG / cut-path files on an order#

Production exports (PDF, vector SVG, cut path) are generated on Starter and above. On Free you still get the production PNG. See Production Files & Preflight.

A customer says they can't submit their design#

Preflight warns about safe-zone violations, too-small text, and bleed coverage — and required fields must be filled before submit. The warning text tells the customer exactly what to fix. If a template triggers false positives (e.g. a deliberate edge-bleed effect), revisit its bleed/safe-zone settings.

Customer uploads look wrong on engraving products#

If colour photos are arriving for a single-colour process, set auto image filters (threshold or grayscale) on the template so every upload converts on arrival — see Images & Background Removal.

An order has a design, but usage didn't count / counted oddly#

Usage counts paid orders only, once per order line, idempotently — drafts, abandoned carts, and webhook retries never inflate it. The Billing page shows the live count for the current cycle.
