Yesterday (6/28/2023) I ran the below automation with one scraper action (Data in the Background) twice - once it used 14 credits and the second it used 7 credits. Today it is consistently using 7 credits. Ivan told me to report it here for Bardeen to look into further.
I think there was some other automation that I was helping with that had an integration that I did not have connected and it did not ask me to connect when I just wanted to open in builder so I consider this a bug.
I also have seen some inconstancy with double credits. It has happened only once or twice so it is hard to say where did it come from.
The release notes specifically refer to dialog that appears if you click Show Details on a playbook, not the builder. To open a playbook in the builder you need to enable all integrations used in it.
