Using the app on iPhone X it is impossible to click on the resolve button for an incident on the iPhone X. Button / clickable area is slightly visible but impossible to click because of new iPhone X interface elements.
Our mobile team is aware of this issue and they are currently working on a fix that will be released on Dec. 13.
In the meantime, you should still be able to use those buttons if you click on the outer edge. The icons overlap most of the buttons, but the exterior should still be clickable.
Thank you for bringing this to our attention and our apologies for any inconvenience this has caused.
