Google Chrome changed their browser in 2020 to enforce SameSite cookie attribute.
This broke most Shopify embedded apps because they load in an iframe within your Shopify Admin.
We at LAUNCHTIP have taken steps to ensure our apps are compliant with this change but from time to time, we receive merchant reports that they are seeing error messages.
If you are an active Shopify merchant using the Chrome browser, we suggest disabling the enforcement of SameSite cookie. To do so, please check this article here.
