Same here, I can't believe there is no way to go back. I have to s of things around my house that I can just add because I live here, but I don't remember everything, and once I hit a question that I cannot answer from memory, I am stuck.

Same here, but the GitHub thread actually calls that out as a known bug. Swipe from the left. Intention is that clicking sonewhere on the map closes the dialog.

Click into open source on the map (on android). I think for Ios it might be back gesture.
