I have a user who says that every time she tries to access my forum with her iPhone she is forced to go through the verification process. She says she has checked the "good for 30 days" box. I have not heard anyone else making these complaints, and it works perfectly for me. Any ideas about what could be triggering this? I've tried Googling but have found nothing that seems similar, so either it's a unique problem or I'm Googling the wrong thing. I'm using the latest version of the software. TIA.
