Thank you @yukke2tanaka ! For your post and interesting suggestion for Capacity building - Renforcement de capacités !
Video instructions in the Android Capture app are not currently available out of the box, but this is an interesting suggestion. There are a number of resources that could help teach users on how to use the Android Capture app specifically the self-paced online academy digital courses.
Have you check these courses out? They do provide a useful overview on how to use the Android Capture app. (The DHIS2 Online Academy is introducing new courses on our updated training platform!)
Thanks!
