I saw a message about the limited playback without purchasing the iOS app or a Plex Pass account. I previously purchased the iOS app for my iPhone. Can I use this on my iPad, too? If so, what do I need to do to set it up for this Beta test? Thanks.
If both iPhone and iPad are using the same Apple ID, you can. Just need to install both the beta and the App Store versions in the device.
Then, in the beta, go to Settings -> Activate & Upgrade -> Restore purchases.
That should open the App Store version of the app, verify the purchase, and then go back to the beta version to finalize the activation.
