Cookies when using separate Dyno for react frontend and Django backend
I ran into the exact same problem while using herokuapp.com.I even posted a question on SO here.
According to Heroku documentation:
In other words, in browsers that support the functionality, applications in the herokuapp.com domain are prevented from setting cookies for *.herokuapp.com
Heroku blocks cookies from frontend.herokuapp.com and backend.herokuapp.comYou need to add a custom domain to frontend.herokuapp.com and backend.herokuapp.com
