Needs Help

This app has an awesome AR feature to get you around the event but the first time I saved all of the sessions I wanted to attend it didn’t save them. So the next time I opened the app I had to go through all the sessions again! Really annoying!

Also, I can’t reserve sessions. It just loads forever and never lets me actually reserve and the standby line is the worst.

Great in theory...

Unable to actually manage sessions across devices/platforms. Sessions starred on desktop web browser do not show up in app. Cannot manage reserved seats in app. Sessions that are reserved cannot be cancelled. Sessions I want to reserve, cannot be reserved. Please try to update quickly so can be usable while at I/O!

Hi Minionman,

Reserved sessions can be cancelled by tapping into the session details and pressing the cancel button or tapping the reserved ticket in the session list. If you have the names of the sessions that aren't syncing properly or aren't reservable, please file an issue on our issue tracker with the session names and we'll investigate:

Thanks for the feedback!

Horrible user experience. The app is constantly doing work on the main thread, freezing the ui. Sometimes I can't even switch tabs without killing the app. I expected more from an app for an event like Google IO.
