Hello Alejandro,
Please take my sincere apology for the delayed response.
The "Page builder pro - agency" plan has support for the SP page Builder only. For a long time that plan was in our pricing plan page. You can even ask other users of us, never there was primary template support for the Page builder pro - agency plan. The Page builder pro includes layout bundles/page templates, if this is what you meant to say.
Yes, we have changed the pricing plan page and structure, what we felt it would be convenient, as our many users were facing dificulties to figure out the template/SP Page Builder plans separately.
Again sorry for your experience. But I guess you had template plans too before, that's why you could access our primary templates that time.
Moreover you can ask any other users, they will assure you that, our "Page builder pro - agency" plan didn't has any template access anytime.
Best Regards
