Why is my transaction being automatically converted to the default currency (HKD) for deduction even though I have activated the multi-currency transaction functionality?

In the following consumption scenarios, transactions will be automatically converted to the default currency (HKD) for deduction:
  • The multi-currency transaction function supports the currency switch, but the current account balance for this currency is insufficient
  • The multi-currency transaction function does not support this consumption currency
  • The currency switch for multi-currency transaction function is not enabled
