ChatGPT + Grok Android login failure — browser works
Samsung S25 Ultra, Android 16. ChatGPT and Grok apps both fail to complete login. ChatGPT shows “Sign-in request cancelled by ChatGPT.”
– Login works normally in Chrome.
– Chrome is default browser.
– Cleared ChatGPT + Chrome cache/data.
– Android System WebView is installed/up to date.
– Google Play Services is up to date; cleared cache + force stopped.
– VPN off, Private DNS automatic.
– All apps updated.
– ChatGPT works when installed inside Samsung Secure Folder.
What Android authentication component/settings could cause the login handoff to be cancelled in the normal profile?
