#1

Hi,
I made Firebase connection and able to retrieve data as described in the Firebase Connector video.
But unable to make the login work on desktop preview app. After entering email and password Failed to login alert pops up.

On mobile I’m able to login with no problems.

Any help will be appreciated.

Depending on the sign in system you use, it might be needed to add the web app options in the data connector.
In general, when you want to use the web preview, you need to configure for web app too
