Some Magnets users experience problems with the photo picker.
When opening the photo picker to upload a new picture, typing something into the search field, and then scrolling down, the photo picker might close itself unexpectedly.
We're able to reproduce this bug and are always looking out for a possible fix. However, as of right now this seems to be a bug of the photo picker itself, and has to be fixed by Apple. We will update this article once we find out more. Sorry for the inconvenience!
