When attaching a photo in the mobile app, it seems the edit is saved during the attachment. The save button is grayed out, and the only way to close the transaction modal is to click cancel, which is confusing for users.

The transaction modal should ideally allow clicking "Save" to confirm the attachments. Otherwise, the modal should automatically close after an attachment is added (in which case there should be a confirmation message), but this may not be ideal if users want to add multiple attachments.
