Thanks for the reply. I’m having the problems on an iPhone 7 using the built-in Safari browser. (The site is fine on my MacBook Pro and iPad.) If I use the mobile skin and go to MyFlyerTalk, I only get a list of subscribed forums and not the old list of subscribed threads with new posts. If I then choose to view the main site, the text is tiny, and any attempt to resize the text makes the ads float over the text.
I’d be very surprised if this is unique to me, as I’m on as standard of a mobile viewing experience as could be — iPhone plus iOS plus Safari. Thanks.
