Yes you also have this issue if you stop the page load mid-way through on the checkout. Cart is emptied and customer logged out

and the minicart still shows the items after this logout happens

Actually the 2 times hit happens on every button or link that points to cart or checkout. Hit twice checkout button on cart page. Why would I hit twice: high traffic, server isn't serving pages fast enough or I just don't see in browser that the next page is loading - sent request. The following statement isn't related to the current issue: hit checkout button on cart page while cart page sections are still loading.

@daniel-ifrim @Zaylril is it still reproducible for you on 2.0.9 or 2.1.11? if so, please clarify if you use secure catalog and secure checkout.

Tried double hitting F5 on checkout and didn't reproduce the issue. Version 2.1.1.

[tkotosz]

I can reproduce this issue in 2.0.6, but it seems it is fixed in 2.1.1

@SerhiyShkolyarenko I don't have 2.1.1 anywhere. If it works for you it works for any than. Thank you!
