A very odd problem with the iOS application (1.7.1, iOS 6.0.1). I have about 70 feeds and, by default, the iOS application is scrambling a large proportion of the names of them.
The error is not systematically reproducible, but I see roughly the first 12 feed names correct, then those repeated several times over the entire list. Tapping any entry changes the name to the ‘correct’ value and opens the ‘correct’ feed, and also seems to fix the names round it but scramble others …
This issue has withstood everything up to and including a hard reset and restore from iCloud. (There is no issue with the feed list in browsers - everything is correct and sorted as expected).
