Thanks for highlighting this. I did wonder if I’d done something similar - there’s also some chatter around some of the 3rd party extensions eating credits.
This morning I found my quotas were suddenly at 100%. That was way before the quotas were due to be reset. Today, although I’ve not used it heavily, the quotas have stayed at 100% (using pro low as I’m implementing and bug fixing rather than doing anything architectural). So either the AI gods have smile upon me, or somebody’s tweak whatever was causing the issue!
