Hello everybody :) So we have this Umbraco 8.18.4 website where we found an issue regarding members that were created through the member service. Initially, after the member is created using the API, property values are added as expected. But if I perform a login using Members.Login(username, password), the property values are removed right after that. I have included a screencast that explains the problem: https://vimeo.com/745387149/0c6d075bdd

And my controller used for both creating the member and performing login looks like this. What are we doing wrong? Hope someone can help :)

public class MemberController : UmbracoApiController
{
    private readonly IMemberService _memberService;

    private readonly string email = "user@domain.com";

    public MemberController(IMemberService memberService)
    {
        _memberService = memberService;
    }

    [HttpGet]
    public void Login()
    {
        Members.Login(email, email);
    }

    [HttpPost]
    public void Create()
    {
        string memberTypeAlias = "Member";

        IMember member = _memberService.CreateMemberWithIdentity(email, email, email, memberTypeAlias);

        member.SetValue("customerNo", "d20001000");

        _memberService.SavePassword(member, email);

        _memberService.Save(member, false);
    }
}
