Thank you. The more people who report system bugs such as this one (a disabled sound still playing) the quicker Duo might fix them. https://support.duolingo.com/hc/en-us/articles/204728264-How-do-I-report-a-bug-
True. However, in the colloquial language, which is what we cover on this course, Byddwch! and Ewch! are the usual form of an instruction or command, whereas Byddwch chi and Ewch chi are the usual forms for straightforward future forms of bod and mynd respectively.
(In more formal registers, the chi or other pronoun is often dropped.)
