Symptoms

You request a login link but nothing arrives, or tapping it opens the homepage or a signed-out page.

Why it happens

• Requesting the link for an address that is not the one on your account
• Link filtered into spam or Promotions
• Expired or already-used link
• Email apps open links in an in-app browser that does not keep the sign-in
• Browser cookies blocked
