When you try to access the app dashboard through your Shopify admin area, you might see a page asking you to enable third-party cookies.
This page provides instructions for enabling them in the most common browsers and devices.
Go to chrome://settings/content/cookies in the address bar and toggle "Block third-party cookies".
Open the Firefox preferences, select "Privacy and Security" on the left-hand side, and set the dropdown next to "Accept third-party cookies and site data" to "Always".
Click "Safari" in the top menu bar, then click "Preferences". Select the "Privacy" tab and untick "prevent cross-site tracking".
If you are using Safari on an iPad, open the settings app, select Safari on the left-hand side, then scroll down a bit until you see the toggle button that says “Prevent Cross-Site Tracking”. Toggle it to the off position.
