why this is worth 20 seconds
A tap from Instagram, TikTok or X opens inside that app's own browser. Google refuses OAuth there and answers disallowed_useragent.
Your sign-in button does nothing. The visitor leaves, and your analytics record a referral that never converted.
This check reads the page a stranger would land on and tells you which buttons are in that position. Nothing is stored about you, and we never post anywhere.
