Where the buying flow shifted
Cross-market eligibility should be readable before recommendation starts.
Explicit country and language support rules reduce wrong-intent inquiries and unnecessary support burden.
Do not trust one metric
The signal matters when it clarifies the buying path, not when it adds another isolated commerce feature.
Check the transaction boundary
- Add a market qualification matrix and link it from checkout/payment and support pages
- Keep the test narrow: one priority product or checkout flow before expanding recommendation, authorization, payment, and support work
What still needs proof
Ambiguous region support leads to unqualified inquiries and churn. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
