If you are experiencing issues with VivaCut not approving or importing new fonts, here are the key points and troubleshooting steps based on the available information:

- Supported Font Formats: VivaCut only supports uploading fonts in the .ttf and .otf formats. Make sure the font files you are trying to import are of these types2.

- Platform Limitation: The ability to upload custom fonts in VivaCut is currently available only on Android. iOS devices do not support this feature within VivaCut at this time2.

- Common Issues Preventing Import:
- The font file is not in a supported format (.ttf or .otf).
- You are using an iOS device (font upload not supported).
- The font file might be corrupted or too large for the app to process2.

- Troubleshooting Steps:
- Ensure the font file is either .ttf or .otf and try re-uploading.
- Update VivaCut to the latest version to make sure you have access to the newest features and bug fixes1.
- Clear the app cache and data, then try again (on Android: go to device Settings > Apps > VivaCut > Storage > Clear cache/data)1.
- Restart your device after clearing the cache and before testing the import again.
- If you have VivaCut Pro, ensure you are logged in with the account used to purchase Pro for full features2.

- If Problems Persist: If you are using supported file types and still facing issues, VivaCut suggests you email their technical support. Include screenshots, the font file, and your email address for further assistance2.

- Alternative Apps: If you continue to experience trouble, you might consider using alternative video editors that support font importing, such as Picsart or Renderforest, as suggested in user forums58.

Summary: VivaCut restricts font uploads to .ttf and .otf formats on Android only. Make sure your files and platform meet these requirements. If all else fails, contact their support with detailed information about your issue2.
