If you have a paid plan but are experiencing issues converting files, this could be due to several reasons:
1. Browser Issues: Try clearing your browser cache and cookies, or try using a different browser
2. Account Sync: Make sure you're signed in to the correct account that has the paid subscription
3. File Format: Ensure your file is in a supported format and within size limits
4. Temporary Server Issues: Our servers might be experiencing temporary issues
5. Subscription Status: Verify that your subscription is active and payment is up to date
If none of these solutions work, please contact our support team with your account details and a description of the issue.
