I just took a look at my usage history, it too is a random collection of some of my journeys but with many (possibly a majority) missing, including all the times from this month (at least 4 journeys) although I haven’t experienced any recent problems during use.
I’m an annual member and once every few weeks I do suddenly find I’m unable to take out a bike anywhere until the next day or so. My balance display has also been permanently stuck at “£-1.00″ since sometime last year.
Who develops the software development for Boris Bikes? Because whoever they are, they’re shockingly bad!
