1. We have a landing page made on Tilda Publishing platform: https://tilda.cc
2. We integrated into the landing Shopify Buy Button: https://www.shopify.com/buy-button
3. We want to promote this page with Adwords and we maintained Adwords setup and connected it to the landing page.
Unfortunately, when somebody clicks a link on Adwords ad, we can't see the traffic source in Analytics. All the transactions marks as direct/none. How to fix it?
