Discount code not applying on PayPal checkout

Topic summary

Customers paying via PayPal are charged full price even after applying discount codes; this began recently despite no store changes.

Reports span several merchants over a few days and affect both manual codes and automatic discounts.

Impacts include unhelpful PayPal support, non‑refundable merchant fees, and one merchant deactivating PayPal as a temporary workaround.

One store hid the PayPal in‑cart button, yet the issue still occurs intermittently and is difficult to reproduce.

Update: the original poster says PayPal seems to have resolved it for their store, with discounts applying again for about a week.

However, another merchant still sees free delivery codes failing when customers complete via PayPal Express Checkout.

Clarification: discounts apply only if customers reach the Shopify checkout where codes are applied or auto‑applied; using dynamic “Buy Now” or accelerated PayPal buttons that bypass checkout means discounts won’t apply. Next step suggested is to contact Shopify Support for account‑specific assistance.

Status: partially resolved for some, ongoing for others; uncertainty remains whether a PayPal glitch or checkout button behavior is causing the remaining failures.

This is still affecting my store - every PayPal transaction seems to accept the discount code on checkout but then will process the full cost without discount applied. Does anyone have a solution for this?
