Memrise Annual Subscription Ended Unexpectedly

I purchased an annual subscription to the language learning app Memrise, but the experience has been frustrating. While using the app, it suddenly crashed, and when I logged back in, my subscription appeared to have ended prematurely. Despite paying for a full year, I no longer have access to the premium features I subscribed to.

I attempted to reach Memrise support through Twitter, but I received no response. This lack of customer support is disappointing, especially when dealing with a paid service. I need urgent assistance to restore my subscription and access to the features I paid for. Please address this issue promptly, as I want to continue my language learning journey without further disruption.
