You try to reinstall QR Queen in Pipedrive and the "App already installed" message appears. This means the app is still installed on your Pipedrive company.
Steps (resolve)
In Pipedrive, go to "Tools and apps" > "Marketplace apps" > QR Queen.
Click "Uninstall" to actually uninstall the app on the Pipedrive side.
Then restart the installation or connection from QR Queen.
Good to know
Key point: removing the link on the QR Queen side (disconnecting in the Integrations tab) does NOT uninstall the app in Pipedrive. The uninstall must be done from the Pipedrive Marketplace.
When you uninstall on the Pipedrive side, Pipedrive notifies QR Queen (uninstall callback) and the cleanup is idempotent: a later reconnection starts cleanly like a new installation.
