Which exact Umbraco version are you using? For example: 8.13.1 - don't just write v8

v9-rc004

Just to add, the sign-in method used is:

var member = await _memberManager.FindByEmailAsync(model.Username);
await _memberSignInManager.SignInAsync(member, false); 

Found in:

private readonly IMemberManager _memberManager;
private readonly IMemberSignInManager _memberSignInManager;

This isn't working for me either using the partial view macro snippets. When I log in I can see that I'm definitely logged in but going to the protected area kicks me back to the login page.

I've made sure to check that the member is in the correct role, should have worked.

I think we're getting the "wrong" HttpContext here somehow. Seems related to #11155
