Does anyone know how long it takes from a parent paying to the childminder receiving a payment in their bank account when using the Tax Free Childcare scheme?

I had a parent use this for the first time, and she said she received a message stating "your childcare provider has been paid". I don't expect it to be instant, but am curious how long I need to wait.

I logged into my Tax Free Childcare account, expecting to be able to view pending transactions, like you can with childcare vouchers, but there is no such facility.
