Additiona instructions for new iDeal implementation:
In TEST environment, if you already have iDEAL added as a payment method, you are probably using the acquirer account iDealSim. This is the simulator for the old flow and will break with this new feature.

Solution: add iDEAL in Customer Area again and make sure the acquirer account added this time is AdyenIdeal. This is the acquirer account for the new flow.

Note: in LIVE, the change to the new flow works ootb, no change in payment method setup in Customer Area required.
