The annotate/draw option in survey123 is a really useful tool that I am currently using in a survey set up for contractors to communicate project progress on a pre-drawn grid. However, the tool can be frustrating to use if you need to make more than a couple of annotations. For example, drawing on the grid often causes previously created notes/lines to completely disappear or change colors randomly. The undo button will sometimes correct this behavior, but often it is necessary to erase the annotations completely and start over.
Is this a known issue and/or does anyone have any suggestions for working with annotations more efficiently?
Note: could this be an iOS problem? We have tested on multiple devices, but they are all iOS.
