The issue, to be clear:
1. When trying to reply to a notification using Alexa we get a "transcription" error.
The root, in my testing has been:
1. The notification is cleared in the phone, before the Alexa reply is complete.
So if, for example, your phone is not locked and the screen is on and a message comes in you will not be able to reply to the notification. The reason is that, as in mentioned in other community posts, the versa will only keep notifications until they are cleared on the phone. The OS (Operating System controlling the phone) may automatically consider the notification as cleared if the phone is unlocked and with the screen on. This will happen even if you do not take an action on the phone to clear the message.
When Alexa/Fitbit attempt the reply the notification is "gone" and we receive the "transcription" error. I believe this is a bug, and will likely be fixed in a future update.
On android they may be cleared in the lock screen as well:

To test this, you can lock your phone and have someone send you a message. If you unlock the phone first you will likely see the error.
Anyhow, that is the behavior I noticed so far. Hope this helps the next person...
