I have ignored the master branch in the config.yml:
version: 2
jobs:
build:
branches:
only:
- develop
ignore:
- master
Can you check why develop branch is not being picked up?
Can you let me know what VCS you are using? Also, is the branch still an active/open branch within your VCS project? If so, try unfollowing and following the project again within CircleCI.
If you are still unable to see your branches, I would recommend creating a support ticket, and we will be able to help you further there. However, for now, you can work around this by adding ?branch=develop at the end of your project URL.
