I contacted apple again, because Anthropics Team are talking to free-tier anymore. Everything is self-service with their Fin AI, and I cannot get in touch with them. Although we are paid users, but since we paid via Apple, the payment doesn't pass through, so Anthropics treats us like free-tier ones.
The advisor suggested that I reach out to the app developer after paying again, in the next billing cycle, like resubscribe to take advantage of my previous plan. While Apple acknowledges the issue with this payment, I’m unable to either refund or use it at the moment. The best option offered by Apple is to wait until the next subscription to resolve the problem with the current one?
But they did say "All is documented here and forwarded to our software team to get the application further evaluated and investigated on."
If some one solved this same problem, maybe we can share the solution?
