Have done all necessary updates and have latest versions of all software on my iPhone, Tivo Stream and Tivo Premier. Have done Streaming Setup OK with "setup out of home streaming" checked and it went fine. Can stream and download fine on home wifi network to iPhone.
Should I expect this to also work with my iPhone when out of the house using a mifi device? Both watch and download are greyed out in that case.
From the Tivo iPhone app's perspective it's still wifi, unless either it or the Tivo video proxy servers are doing a tracert and detecting mobile networks in between the two of them.
I read this thread but it's not exactly the same question:
Have raised a case with Tivo Support but it's not clear whether they understand what I am asking and we have been back and forth a couple times.
