If you're having trouble linking your eToro account to Delta, try the following steps.
Reinstall the Delta app: Remove Delta from your device and reinstall it from the App Store or Google Play. This resolves most app-level connection issues.
Force a portfolio refresh: Go to Settings > General > Primary/Secondary Fiat Currency. Swap your primary and secondary view currencies, then switch them back. You can also tap the Total Worth figure on the Portfolio page to toggle between currencies — this forces a full recalculation.
Make sure you're running the latest version of the Delta app. If the problem continues after these steps, contact our support team.
