Selecting the Get it now on the Marketplace for the Git Flow Bitbucket Cloud add-on leads to a blank page

When attempting to install the Git Flow (https://marketplace.atlassian.com/plugins/net.collabsoft.plugins.stash.gfc/cloud/overview) Bitbucket Cloud add-on directly from the Marketplace the add-on isn't found in BB Cloud when the user is re-directed there:

Steps to Reproduce

1. Select the Try for Free button on the Marketplace listing
2. Select Get it now for BB Cloud version. (https://bitbucket.org/repo/LboRq/images/494513950-Screen%20Shot%202017-03-13%20at%2010.00.04.png)
3. User is redirected to BB Cloud but now results for the add-on are found in the integrations section. URL is

   \\
   https://bitbucket.org/account/user/chparker2/addon-directory?addon=net.collabsoft.plugins.stash.gfc\\
   

The add-on is in the registry as it can be seen in Find Integrations, other add-ons are working as expected.
