When I do payment with Mastercard on FlexWin offsite redirect DIBS returnig status core 12: capture pending.
I makes payment with pending status that will get completed after it would be claimed by merchant.
On the commerce side payment would be note created and checkout process would fail.
Add handling for "capture pending" status, with delayed regular check on transaction status.

To get ability use pending statuses this might need this issue resolved.
