I have been using Disney+ on my stream 4k without issues. Today when i opened it, it ask me to log in. I know this may happen time to time. However, when i get to the screen to put in my email/username, I click on it and the on screen keyboard does not come up.
Te other option it said is to open up the disney+ app on a mobile device connected to same network. I did that but it didn't do anything.
I didn't have a BT keyboard, so finally had to download a BT keyboard app on my phone to mimick a BT keyboard.
