There never was one..? At least I don't remember it being a thing tbh.

Was around 4.1 that they removed it, apparently.

I checked it out of curiousity, and patch notes didn't mention any changes about amount of books you could use. Do you by any chance mean this phrase from official page for level boost system? Because its wording does sound a bit confusing for sure.

Instantly level one job of your choosing to level 70, complete with a set of gear to begin your adventure.

Though I won't be surprised if there was some sort of a bug or restriction, but in this case that's a bit weird that they never wrote about lifting/fixing it.

Truthfully, I just remember about jump potions from a love letter back in the day with initial discussion about it being a one time thing per character... but I never really followed up with it after it went live. A quick google search about it pulled threads on here that said the restriction was lifted around 4.1 due to poor sales.
I can’t honestly confirm any of it as I never used, and if/when restrictions were lifted (or even ever implemented when the product officially launched), I’m not sure as I kinda glazed over it other than the initial discussion on live letter.

It could very well have been that second bit you mentioned,

Now that I googled it, I did indeed find some threads about restriction (on reddit mainly), so looks like you remember it right. Though it's confusing that I didn't find a single word about changing the system at lodestone. Maybe my key words for searching were wrong.

P.S. Wait, I found it. They just wrote about it in Mog Station new items release post, not in normal patch notes where I looked for that. My bad.
