Testing the Rails Shopify App with Capybara & Cucumber (updating the Shopify plan during testing causes an authentication error)

Question

I have a Shopify Rails application, and I'm trying to test some of the features of my pro plan, but I could not update the test store plan. I can log in without problems, but when I try to update the store plan through capybara, I am redirected to the login page.

I have some troubleshooting problems, but I really don’t know where this problem comes from, because it works fine when I try it manually in my browser. Maybe a problem with the database or caching?

Here are my cucumber steps (basically, just log in to the application, select a plan):

Background:
    Given I am a logged in user
    When I am on the pro plan

Capybara:

When "I am a logged in user" do
  step "I visit the login page"
  step "I supply my shopify url"
  step "I get taken to the app index page"
end

When /^I am on the (.+) plan$/ do |plan|
  click_link_or_button "Settings & Notifications"
  click_link_or_button "edit plan"
  choose("shop_plan_#{plan}")
  click_link_or_button "Update Plan"
  click_link_or_button "Approve charge"
end
