Could always connect for a quick tutorial/lesson, I am free as early as tomorrow. Or there are some great online courses some users have made available - just use the search box on this forum and try typing “Bubble course” or “Udemy”
Also try typing “User Type” in the forum search, there are many results so I am unsure what one would be most relevant without knowing more about your app goals
My early days on Bubble I used this example app to learn basic functionalities (although it separates Users slightly different than I described above)…
