To address the issue with the Tonquin app not allowing you to upload documents, follow these steps:

1. Check Your File Format: Ensure that the documents you are trying to upload are in a supported format. Common formats include PDF, DOC, and JPEG. If your document is in a different format, convert it to one of these compatible formats.

2. Reduce File Size: Large file sizes can cause upload failures. Try to compress your documents or reduce their size using tools or software available online.

3. Clear App Cache: If you are using a mobile version of the Tonquin app, clearing the app's cache can help resolve many issues:
- Go to Settings on your device.
- Navigate to Apps or Application Manager.
- Scroll and select the Tonquin app.
- Tap on Storage and then Clear Cache.

4. Ensure Stable Internet Connection: Make sure that your device is connected to a strong and stable Wi-Fi network. Poor connectivity can lead to upload issues.

5. Update the App: Check if there is an update available for the Tonquin app. Developers often release updates that fix bugs:
- Go to your device's app store.
- Search for Tonquin and see if an update is available.

6. Reinstall the App: If clearing the cache and updating the app doesn't work, consider uninstalling and reinstalling the app:
- Uninstall the Tonquin app from your device.
- Go to the app store, search for Tonquin, and reinstall it.

7. Contact Support: If none of the above solutions work, you can reach out to Tonquin's support team for assistance. You can contact them via email at [email protected] or call them at (855) 484-2420 - learn more.
