If you encounter the "invalid email or password" error message when logging in to the Evey Check-in app, it's likely because the email you're using corresponds to your Shopify credentials but hasn't been added to the Settings > Check-in accounts section yet.
Here's how you can resolve this issue:
1. Access the Evey Events app.
2. Navigate to Settings > Check-in accounts.
3. Click the "Add User" button.
4. Add the email associated with your Shopify credentials.
5. Save the changes.
Once you've added your email to the Check-in accounts section, try logging in again with your credentials. You should now be able to access the app without encountering the error message.
