Applies to /account/settings
Choose language, display currency, and light or dark mode. System mode follows the setting on your device.
Each choice is saved to the account at once, with no separate save button, and applies on every device you sign in from.
The currency choice only changes how amounts are shown. The source amount, source currency, rate source, and rate timestamp stay unchanged, and an estimate never becomes an appraisal because you switched display currency.
