Flow with HTTP file download runs forever

Hello everyone, 


I built a flow downloading PDFs (10-20MB) from our sales side to a SharePoint library with the goal to have the files available offline on the onedrive app. 


For configuration I have a SharePoint list to enter the necessary download id and where to store it in the subfolder. 


If I only check 4 items in my list the flow finishes within 30 minutes. Processing all 12 takes almost 2 days (the data transferred is about the same for all items in the list. Expecting about 3 hours of runtime) 

This is how the flow looks. 


Concurrency Control is enabled in both loops. 

Looking at one finished run (note I have removed the variables which I needed for debugging) I can see, that one loop ran 2 days. 


All actions within the loop took no longer than 10 seconds. 


Do I hit a Flow limit? Can anyone help me with that?

Could you try to activate concurrency control and set degree of parallelism to 50 in the apply-to-each action that took 2 days? (settings in the apply-to-each):



Hope that helps!
