You've set everything up and Shake is working, but it's not sending feedback and the console says something along these lines:
E/Shake (13570): retrofit2.HttpException: HTTP 401 UNAUTHORIZED
This can be caused by:
the wrong API key used in Shake.start → Please verify that your key is copied and pasted correctly
(only Web SDK) wrong domain name used in Shake.start → Please verify that domain name used in Shake.start is matching domain name of your app on dashboard
(only Web SDK) app not marked as localhost → Please check "Localhost build" checkbox when creating a new app for localhost
This always helps. If your problem still persists though, click the bubble in the bottom right corner and let's chat. We'd really like to help you.
