Hey there @lizfltn!
Thanks for the detailed description of the issue you’re seeing 
Considering this is happening without a social provider involved, I don’t think there’s an issue there - This is good news as that can get tricky!
I believe this is related to the defining your app’s auth0Scheme as https like:
manifestPlaceholders = [auth0Domain: "@string/com_auth0_domain", auth0Scheme: "https"]
Instead, you might try setting this to a custom one (In our sample apps we use demo for example). Here are some further resources on this:
Hope this helps!
