That makes total sense now! Thanks for the clarification.
I’m not quite sure what you mean by “Legacy Legacy” and “Legacy”. I think you’re alluding to the fact that previously it was possible to never consume your trial credit, because the free allowance would be consumed first?
Yes exactly, but with your explanation it makes sense now. Basically it’s not a new major version of the Hobby Plan, just a fix 
So if I want to continue to have a completely free usage, I need to switch to PAYG and make sure that I’m below the 5$ limit, right?
Do you mind confirming this? So I can make this change with more confidence
