Litmatch Device Banned Without Explanation and Account Access Blocked

I have been using the Liitmatch application by logging in with my Apple ID. For more than a week, whenever I try to open the app, I get the message “The device you logged in has been banned, please log in with another device,” and I cannot access my account from this phone. I do not know the reason why my device was banned, and I have not received any explanation or warning inside the app or by email. I only used my personal account on this device and did not knowingly violate any rules. I request that my device ban be urgently reviewed and removed, or at least that I be given a clear explanation of why this ban was applied and what I need to do to recover normal access to my account.
