Please note that in Listening Mission, sentences are split into blocks based on the spacing of the assigned sentence when you make edits.
For example, if the sentence is "Come join Litto's Listening Mission.", it is divided into 5 blocks (Come / join / Litto's / Listening / Mission.) and edits can only be made within each block.
In addition, each block allows up to twice the number of characters of the original word. (e.g., the "Come" block allows up to 8 characters.)
This is applied at the system level to prevent words within a sentence from being modified indiscriminately. We appreciate your understanding.
Thank you.
