Compatibility issue with WooCommerce

Hello,
I have been using your plugin on my site. Now when I am adding WooCommerce, there is a weird scenario happened.
Steps to regenerate:
1. Go to shop page when login.
2. Go to any product page.
3. Back to shop page using the browser back button.
So when you are coming back to product page, it is displaying that you are not logged in. Also, any functions that are running on basis on conditions that users logged in is not running properly. After giving a page refresh everything will started working properly.

I have also checked this with a default woocommerce setup where only woocommerce and email-address-encoder plugin is available and active.

Hope to get a fix quick.
