Hello @Key-Library
I had look over store and the functionality you created for add to cart “Login/register to see price” may be the cause to not adding products cart and empty the cart items.
Briefly i can let you know once i look over backend of the store.
Topic summary
Customers report Shopify carts emptying unexpectedly across devices, harming sales and prompting some to consider switching platforms. The issue predates a newly added “login/register to see price” feature on one store and persists even after switching to a 2.0 theme.
Key investigations and actions:
- Collaborator access requested to inspect backend; multiple experts involved but no definitive fix found.
- Several stores tested themes and concluded the theme isn’t the cause. One merchant suspects a third‑party modification or app.
- Apps reviewed; Shopify Search & Discovery and Email were suspected by one user, but another had cart loss before installing Search & Discovery, so no clear app culprit.
- Behavior appears intermittent: carts can persist 1–2 days, then empty after 3–4 days. One store noted no abandoned carts recorded for affected customers.
Latest development:
- A Shopify Plus merchant reports Shopify resolved their issue, attributing it to insufficient server RAM on Shopify’s side rather than app or theme code.
Status:
- Partially resolved. One Plus store is fixed via Shopify intervention; others remain affected and are seeking the right Shopify contacts. No universal root cause identified; the discussion remains open.
