I purchased lifetime tier 3 in Aug 2024, shouldn't I have all the new features, as per the "lifetime license deal"? How can I get them?

"Deal terms and conditions: Lifetime access to Boardmix. All future Business Plan updates. All future AI model updates. If Plan name changes, deal will be mapped to the new Plan name with all accompanying updates. Previous AppSumo customers will be grandfathered into any new features and feature limits."
