Hiya.
I've got this problem. My site is using two separate management systems.
One quite simplistic lightweight for the main site, other one (magento 2) for the store subdomain.
Is there a way I can Implement the Subscription form from the magento to my main site?
I tried to copy the form over and what happens it takes me to the store and displays Invalid form key error message.
Any tips. Magento is still like a black box to me even though I've had it deployed for a while.
