In your personal account, go to the Users section, enter the profile of the required client, in their profile go to the Playlists section and click the Copy Sorting button(1)
In the pop-up window, select your sorting profile, which you want to apply to your sub-user.
For example, System Profile(1)
or a profile you created, in the screenshot Profile 1(2)
After selecting the profile, you need to click the Copy(3) button and your channel sorting will be applied to the sub-user you selected.
You should repeat this process with each of your clients to whom you wish to copy your sorted channel list.
If you reset your sorting, it will not be reset for your sub-user. To reset the sorting for your sub-user, you will need to log into the personal account with their username/password and reset the sorting from their account.
