Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

Source: Official docs (Frontegg Android usage): documents a gotcha that trips agents switching the Android SDK to hosted login. Chrome Custom Tabs hosted auth only takes effect if you disable the EmbeddedAuthActivity and enable the HostedAuthActivity in AndroidManifest.xml with tools replace on the enabled attribute. The same page documents switchTenant for multi-tenant users: pass a tenant ID taken from the session user's tenantIds list, not a tenant name or slug.

Verified resolution: To use hosted login on Android, add both activity entries to the manifest with the enabled flags flipped and tools replace set, otherwise the SDK keeps using the embedded WebView. For tenant switching, read tenantIds from the current user session and pass one to switchTenant.
