Magento 2 - invalid form key (add/delete from cart)












0















I have serious problems with custom Magento 2 theme and (probably) formkey cashing. I have 2 views of exactly same e-shop.



 - View 1: Luma Theme
- View 2: Custom Theme (Luma child) - overriding layouts, phtml, styles and javascripts


If cache is enabled and flushed everything -> adding/deleting from car works properly. After several minutes specified actions in View 2 (Custom theme) returns 302 status code and Magento redirects user to /cart page.



Now i discovered 3 ways how to "fix" this issue.




  1. Flush cache - only temporary solution for few minutes.

  2. Delete formKey validation from Magento core - totally inappropriate.

  3. Disable cache - affects performance.


I'm struggling with this problem couple of days and I will be glad for any advice.
