The planning of the event beforehand was very good and thorough. Simon sent me the joining instructions in good time to send it out to my team. On the day I felt perhaps the instructions were quite complicated and very detailed, so wasn't entirely clear what we needed to do, and by then the clock was already ticking. In terms of the app – although it was a great use of technology, it was quite confusing to use and some of the images were so tiny you couldn't read them. You could quite easily lose your place as when you clicked back it took you to the home screen and didn’t indicate where you needed to go next. And in terms of formatting, some of the 'handwritten' notes were quite difficult to decipher and you weren't able to zoom in. A few teams also had an issue with who their team captain was (my team being one of them). They had chosen someone and then halfway through something seemed to happen in the background and it flipped to someone else. We called for help, but when they came on, they just said ‘is the new captain ok to carry on’ not really giving us a chance to say no (it actually wasn’t convenient for the new captain but the helper didn’t seem too bothered or give us the option to choose someone else.). I then found out later that someone in my team had become captain for another team, so there was clearly something happening in the system. But it was the way the helper was quite dismissive that I didn’t find helpful. However, apart for theses technical glitches, everyone seemed to enjoy it.
