Hello,

If your eBook isn’t opening on mobile and no option is provided:

1. **Install an eBook Reader**: Download apps like **Adobe Acrobat Reader** for PDFs or **Kindle/Google Play Books** for ePub and other formats.

2. **Check File Format**: Ensure the eBook format is supported by your app (e.g., PDF, ePub).

3. **Redownload**: If the file seems corrupted, try downloading it again.

4. **Permissions**: Ensure your app has permission to access storage.

5. **Alternate Device**: Test opening it on another device.

For more help, contact the eBook provider.

Sometimes open ebooks might be tricky.

Try to check what type of file you have downloaded. If it's a pdf you can use apps like Adobe . If it's word document then you can use Microsoft 365.

You can also use Google drive or one note depending on your preference.

You can also use Google play books if it's EPUB version
