Hi there,

I have developed an eBook for a low vision author who is keen for their book to be as accessible as possible. With this in mind I have made sure the file is compatible with as many eReaders as possible, especially when it comes to Text-to-Speech, which all seem to be working fine.

However, when I use the Send-to-Kindle service to test my EPUB file on my Kindle iOS app, the eBook itself works perfectly but the Assistive Reader function is greyed out and is unavailable.

I cannot for the life of me work out why. Is it something to do with my CSS? Do I need to include a certain line of HTML within the metadata to enable Assistive Reader?

Any help would be appreciated!
