Build not triggered after editing .travis.yml

[xhliu]

I have two private repos R1 and R2, both are working fine with Travis. After slack notification is added into .travis.yml in R1, it still works. However, after I add the same to R2, Travis is not triggered anymore. Any idea? Same slack notification cannot work on multiple repos?

notifications:
  slack: '<account>:<token>#development'
