Catherine Brill from DTSL has given a heads up regarding the Clicker Connect App and updating your iPads to the new iOS8. The Clicker Connect App is having real problems with the iOS8. If you try to delete a cell within a cluster (just the first left hand cluster), and although it looks fine in Edit - as soon as you tap GO, it will have deleted the entire cluster. Catherine has made Crick Software aware of this bug and they will be correcting it in the next update which should be in 2 to 3 weeks time.
