Customer had chosen service plan period and was redirected to the first screen of purchase scenario in Online Store. On the same screen customer had changed subscirption period but price in order details was not recalculated to new period prices. It was updated only after moving forward to the next screen from purchase scenario.
The issue is caused by PBA-73324 "Order info is not updated if change Subscription Period".
