What to do if your Solana (Solflare/Phantom) account balance remains the same after unstaking?

ISSUE:
I have used https://solflare.com/staking and Phantom wallets to unstake some SOL (Solana), though my balance remained the same after numerous days.

SOLUTION:
The Activity tab shown the transaction as Unstaked and finalized, though apparently I forgot one more step and that is to click that Unstaked transaction and select "Withdraw ".
