Erase all data after unistallation - make clean install

I got some issues with node red and decided to uninstall och install the addon again but it seams that the data is still here, it also doesn’t pickup the HA server by auto. Can I force all previously data to be removed and make a fresh installation?

How are you installing node red?

Hass.io / Add on store

The flows and configurations are located inside the addons directory in the hassio share.

Uninstall the add-on
Delete the files
Reinstall the add-on

It was empty but I fund it under “config” - thx, working now!
