I have been a long-term user and have greatly valued the product's evolution since my initial onboarding. The recent integration features have significantly streamlined my workflow on several projects. However, I am concerned that my lifetime subscription was unexpectedly revoked and replaced with an alternative billing structure. I diligently monitor all product updates and official communications, so this charge was both unforeseen and inconsistent with my expectations. Could you please clarify why this change occurred? The initial response I received from the AI chatbot did not address my concerns accurately. While I recognize the promotional campaign has concluded, I would appreciate a formal explanation regarding this adjustment.
