People who use Apple products will have found that something changed a few months ago and they can no longer view recent issues from the archive on their devices.
It appears to be something we changed clashing with something dione by Apple but it's taking a long time to find out what.
Please be assured that the company who prepare the digital magazines are working to try and find out what it is.
If it's any help tracing this problem, Neil, my iPad2 with iOS 9.3.5 does not suffer from this. I can access all the archive issues through this site without any apparent problems. Pocketmags access seems "normal", too.
It's something to do with Safari I think, that also affects Google Maps. Changing browser may improve matters – I fixed the Maps problem for someone at the weekend by installing Chrome on their Mac, and Firefox seems fine too.
