TikTok Shop Registration Limit Error Fix

I need urgent assistance with my TikTok Shop. I recently applied for a TikTok business account and it was approved through the app. However, when I tried to open the TikTok Shop, I encountered a registration limit error. I've created two TikTok support tickets, but they went unanswered and have since been closed.

The ideal freelancer for this task should:
- Have experience dealing with TikTok Shop issues
- Possess strong problem-solving skills
- Have the ability to communicate effectively

Please, I need this issue resolved as soon as possible.
