First of all, here are the rules for using a recovery sentence: A recovery sentence consists of 12 words and all in lower case, and 1 space between the words, no space before the first word or after the last word.
If you get an error message while entering the words then that particular word is wrong. If you cannot continue in the app after completing the recovery sentence then there is also a wrong word between them or the order is wrong or one space too many. You can then compare the words with the word list
