For Blync, we just got notified by the review team that the offer isn’t showing on their end: https://screenshot.click/44894-90619-90774-73511-28140.webm
However, it’s working fine on our end. We’re trying hard to figure out the issue but are unable to because we can’t reproduce.
Can you please make sure you’ve enabled the extension on your Checkout Settings page? If that doesn’t do it it may help to read about Product Offer Limitations and Considerations. There might be something in there that’s causing you problems 
Here’s a clearer and more structured version of your message:
I was able to replicate the issue with the post-purchase flow not showing up by using a US address. I confirmed that this is not an implementation issue — I pushed new code and verified that the necessary pre-condition ({render: true}) is being correctly returned. So from our side, everything is working as expected.
The root cause seems to be related to Shopify’s known limitations: post-purchase upsell offers don’t appear for orders with duties or multiple currencies. Since the test store was originally created in India, Indian addresses work fine. However, US addresses trigger multiple currency handling, which breaks the post-purchase flow. I suspect the test user may be experiencing the same issue.
I also reviewed Shopify’s list of limitations again. The following scenarios can break the post-purchase experience and prevent our UI from showing:
These limitations are beyond our app’s control.
Please let us know what we should be doing.
It’s hard to make any concrete suggestions here with the limited information we have on what you’re trying to do and what’s happening on your store. The most likely explanation is that you’re hitting one or more of the limitation in the product offers API.
I’d suggest reaching out to Developer Support directly (via the Support tab in your partner dashboard) and we’ll be able to help you investigate further from there.
