Pre-troubleshooting check

FireCheckout is using default Magento functionality as basic.

After installation If you have some checkout features not working, please, check following:

• Go to Admin > Stores > Configuration > Swissup Checkout > Firecheckout > General
• Set Enabled > No (please, check if that settings are same at the store level)
• Clear store cache
• Go to frontend, pass to checkout and check if you don’t see that problem at DEFAULT checkout

If an error is still there - please, contact your developer to fix it at default checkout then in most cases it will be fixed at Firecheckout
