"Picture taking form field in campaign A makes the app crash every time we try to take a picture, so we are just skipping it for the time being. It works in survey B though, which makes me think that it is the picture taking form field, in combination with some other data field(s), that the app is not tolerating."

I can confirm that collecting for another survey in my app (picture taking required & can't be skipped) does not work, instead a "Unsaved data restored" pop-up appears. Survey: https://ground.openforis.org/survey/N5hZgxQ8MnKDD8lhDwMs Build 0.1.17

Same does not work reproduced in a survey where the picture-taking can be skipped.
Skipping and getting to the last page ("Data collected successfully") the app fully crashes.
