You will need to go to your admin dashboard and find either the Cash App Link menu or Cash App Pay menu in the sidebar then set up all the fields especially the first one which enables it on the checkout page.
The direct links to set up the payments are:
/wp-admin/admin.php?page=wc-settings&tab=checkout§ion=cashapp
/wp-admin/admin.php?page=wc-settings&tab=checkout§ion=cash-app-pay
Please make sure to enable the first checkbox for the payment of your choice so the payment method shows
Also, our plugin is separate and unrelated to Woocommerce payments.
