Q: Subtasks and GitHub integration

[vitaly_karasik]

I have a Jira issue  (V-551) with a few subtasks (V-552, V-553, ...). 

My github workflow uses a branch per environment, i.e.

1. I commit to 'dev' branch (or via PR from feature branch)
2. open PR and merge to 'staging'
3. open PR and merge to 'sandbox'
4. the same for 'master'

My goals are:
1. To see all details about commits in the relevant Jira issue

2. To see relevant deployment events

I'm using branch per Jira issue (or subtask).

In fact, integration doesn't work in many cases. Deployment shows deploy to staging only, even when my code already merged to the master and deployed to production.  I'm not 100% but it seems that it works less stable for subtask.

My questions are: Does Jira/GitHub integration has an issue with my workflow? Or with subtasks? Is there some detailed doc with examples for GitHub integration?

Thanks,

Vitaly
