That’s completely normal. When you cash out from your RoundUps or a Savings Goal, your Spendable balance will go up, but you won’t see a new line in your activity feed.
The different sections you see in the app (like Spendable, RoundUps, and Goals) are just visual. Your KOHO balance is still one account. If you make a $17 purchase and have $10 in Spendable, $5 in RoundUps, and $2 in a Goal, KOHO will use all of them to cover the cost.
Rest assured, your funds are never lost. Every dollar is accounted for, and you can always track your savings and cash outs in the app under Discover > Save.
