Flow doesn't restake your rewards automatically. They sit in your Rewarded balance, earning nothing, until you restake or withdraw them. Restaking regularly, such as every week or two, lets your rewards compound. To restake:

1. Click Staking in the left-hand sidebar and open FLOW.
2. Click your Flow account to display its stake accounts.
3. Find your stake, open the three dots (⋮), and choose Restake rewards.
4. Enter the amount to restake and click Continue.
5. Review and approve the transaction.
6. Click Close.

The restaked FLOW shows as Committed until the next epoch starts (up to about 7 days), then becomes Staked and starts earning.
