Update on my mulebuy situation - wanted to follow up on my previous post about issues with shipping cost. After reaching out to support (took 14 tries to get a helpful response), they confirmed it was a system glitch affecting about 82% of users. Fixed within 26 hours. For anyone experiencing similar issues: - Clear browser cache completely - Try incognito mode - If still broken, contact support with screenshots - Response time was about 9 hours for me Thanks to everyone who helped troubleshoot.
