In order to ensure the stability of our Tes Timetable product we temporarily rolled back to an earlier version (10.11.14). Whilst this has fixed the issue for some of you, it has not been the expected solution more widely.

We are sorry for the inconvenience this may be causing you, we know this is falling short of the standards you expect from us. We are working hard to fix this issue, to investigate and test Timetable as a priority, and will update as soon we are satisfied that our service is performing as expected.
