I can't understand exactly what policy you're following. In addition to my subscription for the JA Templates, I also have a subscription for the Extensions. Where does that subscription fall? Is it included in the €120 plan—which seems reasonable, since going from €90 to €120 is a 30% increase—or is it part of the €299 plan? If it's the latter, that would mean more than doubling the subscription cost. You need to clarify what you're planning, what you're asking for, and what you're offering in return. Under these conditions, it's simply not possible for someone to renew their subscription, start a new project using a template, or make use of any of your premium extensions. I hope you clarify your position soon.
