When replying to an email on a mobile device it duplicates words whether you use voice-to-text or keyboard. This doesn't happen with other applications or usage on the mobile device. It also does not happen when using a computer to reply to email. This only happens when using Yahoo mail And I'm replying to an email. It doesn't matter who the email is from it is for every single email. It is so aggravating that I'm having to use other email in order to reach out to people if I do it predominantly on a mobile device. I don't have time effort or energy to keep deleting words and letters when Yahoo mail, which has been one that I've used for many years, keeps duplicating everything that I voice-to-text or type. For me it's simple. If Yahoo mail cannot provide a product that is usable on a mobile device, then I will use an email that is usable on a mobile device. This has only been an issue since some upgrade that has recently happened and that occurred with the last change of Yahoo mail. As of right now there is obviously no interest in correcting the problem.
