I do wish the app could generate custom link, but otherwise works great!

We were wanting to provide custom links to 4,000 customers from a partner site. I reached out to the Support Team before asking about links and they suggested a format that would have ended with us sending 4,000 broken links to our recipients. We ended up making new links in Sheets, but that can be tricky with formulas and hyperlink formatting - it would be great if the app could automatically create links when creating the discounts, similar to what Shopify discounts do

Hello, dear store owner,

I have been trying to reach out to you since last week regarding your review and to see if I could help you with something.

I noticed that all code generations you made were successful and had no errors, so it would be really interesting to hear what issues you faced with the app and if I could help to solve those issues!

Please, reach out to me when you have time! dynoapp@xantho.lt

Best regards,

Update:

Hey team,

This is probably a misunderstanding, and you reached out to the general customer support of Shopify and not with me, through the app live chat, as I cannot find any requests from your store.

I'm familiar with the correct format as I have tested it, and I provide instructions on how you can add all the links to any CSV using ChatGPT in 1-2 minutes if needed ;)

But thank you for the feedback, and now it is clear what functionalities you were missing. Next time, I would recommend contacting app support directly using the Live Chat option, and I can provide better help related to discounts and the app itself ;)

Best regards,

Eimantas
