With Infuse Pro on APTV 4K, can I then steam to my iPad/iPhone when I’m away from home?
If you are running Infuse on your iPad/iPhone you can access your media remotely.
There are a few ways to do this, but the simplest would be to placed videos in Dropbox, Google Drive, or OneDrive and have Infuse access them.
Setting up remote access to your share(s) is also possible, a bit more info on this can be found here.
Also, the upcoming 5.7 update will also allow for remote steaming from Plex share(s) if you currently have those set up.
