when creating a new user account, once the relevant profile has been selected and the corresponding user function has been set, it always reverts by default to the Product Owner function, only the second time can the function be edited to the one that you actually want to assign to the user. Why is it that the first time you set it and then save it, it always returns to some default (in our case it is Product Owner) function?
yes, this is normal, hence the term "default", that is, the most common function or profile for this resource.
Since we can change profiles at each assignment and we can assign the same resource with several functions to the same activity, we must select a basic one. The default one.
To best manage the functions, I advise you to go to the resources screen and not to the user, which only records the default function. and you will find the necessary information for managing functions in our manual.
