Nice switch design and functionality is great.

1. The switch should not change position when it changes value. Try to place it in the top right corner of the component.
2. Add a balance header to the Receive page

Switch positioning is much better.

The current implementation (rendering or not rendering the balance based on the switch) may be the best way to do it. However, I still really don't like content jumping anywhere in the app.

Ideally, hitting the switch will not cause any content jumping.

Best case scenario: a hidden balance has a neat effect, like spoilers in Telegram:

Implement this and we'll compare if it's better than the current full-hide version with content jumping.

Feature and styling look great. However, it is annoying that the UI locks when the switch is hit.

On reviewing the changeCashtabSettings function, this UI lock is implemented specifically to prevent incorrect balances being displayed when the fiat currency is updated. This makes sense. However, this was the first setting to be implemented. Other settings changes do not have this restriction.

Please modify the changeCashtabSettings function so that the UI is not locked when this setting is changed.

e.g. one way to do this is to only setLoading(true) if the requested settings change is not this one,

if (key !== 'toggleHideBalance') {
            setLoading(true);
        }
