Tests do not upload.
You will spend a lot of time and energy doing a test using the Playbook UX app only for it not to upload at the end. I attempted the same test twice and each time, the app simply failed to upload the recording. It doesn’t even show any loading screen - it’s just stuck on the Upload Instructions for over an hour. Playbook UX support articles claim that it’s possible to go find your recording in /Library/Application Support/Playbook UX, but this path is only accessible from a Mac and NOT from an iPhone. I see no evidence that anything I recorded has been saved.
