Make sure in advance that the other member receives WGT's automatic mails - the transfer process will send one to him!
WGT's plans are top secret, I'm afraid. No Veteran setting in Android. How about Apple's app?
It might be a question of display space:
At the "permissions" tab, Veterans are on display in a dedicated column, but there are only four permission (lines) visible, though (on PC) there are seven permission options, including "manage Custom Courses" and "email members".
