Some web applications open the file picker from a custom upload button, or from a file input that is hidden, created on the fly, or embedded in an iframe. When you trained a browser test against one of these applications, the mabl Trainer could not always capture the upload, so the file step was left out of your test. The mabl Trainer now records these uploads automatically. File upload steps are captured no matter how the application opens its file picker.
To get this improvement, update to the latest version of the mabl Desktop App. No other action is required: once you are on the latest version, the Trainer records these uploads as you train.
