Howdy, Nick! Thank you for joining our Auth0 Community and bringing light to this issue again. I have been following up internally on this matter and raising the questions and concerns with the appropriate team.
The result of our goal to improve the Auth0 integration experience for Angular developers is the new Auth0 Angular SDK, which is in beta 
This SDK should solve all these troubles. Nick, if you’d like, we are going to host an Angular SDK workshop for developers on Monday 24th August @ 11am PST / 7pm BST. If you’d like to attend, I can send you an invitation. @brandon_sigao, you are also welcome to attend, if you’d like. We are looking to get as much feedback as possible from developers who work with Angular and Auth0 so that we can provide you with an excellent developer experience.
