When you create a form (you are the parent account), you can share the right to add submissions with a child account.
Nevertheless, when you want to fill the form on your device by using the child account link you can not. You need to use the parent acount URL.
It is not normal as a “child” user that you need to enter the parent account URL rather than the child one to add submissions in ODK Collect.
I am using EXCEL 2013, KOBO Humanitarian response & ODK Collect v1.22.4.
I think permiting to use the child account link would make it more logical, as the child user then sends to his own account, to which the parent account has access.
Thank you to take this into account
