DISPLAY101: Customer display snapshot failed
What this means
The customer-facing display could not build the picture of the cart it was about to show, so it fell back to the idle screen.
The till itself is unaffected — keep serving. The display builds the snapshot again the next time the cart changes, so adding or removing a line usually brings it straight back.
Your data
No order or product data is affected. Nothing about the sale is changed by this, and the customer display is a mirror rather than a record.
Troubleshoot
- Carry on with the sale. The till keeps working, and only the customer display returns to the idle screen.
- Add or change a cart line — the display rebuilds the snapshot on the next cart change and normally recovers on its own.
- If the display stays on the idle screen through several cart changes, check it is still listed under Paired displays in Settings → Customer Display, then close and reopen the display window.
- If it keeps happening, note the affected order, use Copy debug info on the Logs screen, and send both to support. A snapshot that fails repeatedly on the same cart usually points at one line item rather than the display itself.
