Hi.
1) Please key in postcode 100 to do the testing, otherwise the shipping rule doesn’t apply.
2) Free product rule setting is in
Woocommerce > Setting > Shipping > Fish and Ships Pro shipping method.
I temporarily turn it off because customers complained that they couldn’t even place an order. there are cart error.
At the time you want to do the testing, you may turn off first & second shipping method, turn on the third Fish and Ships shipping method to do the testing.
Not sure why customer couldn’t even place an order if the shipping method is on.
For both website I am using same setting.
Thank you!
