Hello Emily,
Thank you for your message.
Of course, it is not retroactive. I did some api calls after changing the log level to detailed, before concluding it wasn't changing anything.
Also our control panel make uses of multiple thousand of api calls daily. None of them are logged.
I'll then open a ticket about it, thank you.
Kind regards.
