I have it logged on on my phone, tablet and TV.

Sometimes pain in the a** when you switch off your TV and want to continue to watch on your tablet in the bedroom, usually get the "Someone is watching/using the account, please retry"  error.
Better if you "properly" exit the app on the TV (instead of just switching the TV off directly) but still got chance to receive that error.

Have to wait a bit before the previous session on the TV is "terminated" and you can start using that account on the tablet.

Yeah, Unifi gave 1 year basic Disney+ subscription free when I signed new contract with Unifi.

It has been in effect since last year (exactly April 24, 2024, when Disney+ introduced two-tier plans: Basic & Premium).

I was among the final batch to receive a complimentary two-year Disney+ Premium subscription on October 12, 2023. Recently defaulted to Basic two years later. I’m on Unifi TV’s Ultimate Max Pack.
