Do yourself a favour and watch "Meetings Bloody Meetings" by John Cleese (I recommend the original one from the 70ies that can be found on the internet archive, not the remake on youtube, also by John Cleese). It's a funny 30min skit, well worth watching until the end, with a nice recap in the last 5 minutes. If you follow those guidelines, you will have productive meetings. In particular, with regard to this app, the meeting would have been cancelled way before any need to swipe, because the chairperson would have not scheduled it (or cancelled it if recurring) in the absence of any agenda items. Similarly, swiping without knowing the agenda seems unproductive. If there were real issues involved, you've simply postponed until nearer the deadline.
