Withdrawals won’t be processed on 30 May 2019 in Indonesia due to a public holiday. Withdrawals will resume on Friday 31 May. Due to another holiday on 1 June, Eid Al Fitr’, withdrawals will only be processed on 10 June 2019.
This is because banks do not process withdrawals on a public holiday. Deposits will remain unaffected during this time.
