Howdy all 
Just wanted to share my experience today with the new loop over node that replaced Split in batches node.
First of all the node context iterator is wrong. Had to copy/paste the Split In Batches to be able to pick the correct index, since the exit run counts as an iteration.
Second, it’s not very intuitive; I would expect the exit path to run once per iteration, not an array per batch.
Lastly, both Loop or Split in Batches nodes have a bug when using with Outlook’s download attachments, ending up into situation where an automation can’t be built
Overall, spent a good chunk of hours today with this node and wasn’t able to get the expected result, resulting to a disappointment.
