I understand that it might not be the intended way of using this endpoint but isn’t the rate-limit here to answer this kind of issue ?
I mean, if there really was too many requests done with those endpoints putting the service health at risk, I guess we would get a 429, not a 204 that says all is good when it’s not(?)
So far i have not made anything in batch so I would be surprised it would be a spam issue.
I even created a fresh new app so if there was a quota issue before, there shouldn’t be any on the new app.
