+## stream.place iOS app OAuth flow fails
+
+OAuth flow with stream.place's iOS app (using expo-web-browser's ASWebAuthenticationSession) does not complete. After user approves consent, the redirect from our PDS to stream.place's callback URL is not followed by ASWebAuthenticationSession.
+
+What does work with stream.place: everything else :P
+- Desktop browsers
+- ios safari (regular browser)
+- ASWebAuthenticationSession using the reference pds
+
+What fails:
+- ASWebAuthenticationSession with this pds
+
+Attempted fixes (all failed):
+- HTTP 302/303/307 redirects
+- JavaScript navigation
+- Meta refresh
+- Form auto-submit
+- Removing CORS headers
+- HTTP/1.1 instead of HTTP/2
+- Minimal response headers
+
