This story happened in November, but has escaped my attention until now.
On the 17th November (2020), Pop Player launched on most Freeview Play devices connected to the internet.
The new player provides on-demand content from Sony’s three children’s channels; Pop, Pop Max, and Tiny Pop. The player can be accessed via the portal on channel 100, or the Freeview Play button.
From launch, Humax 4000/5000t and LG devices were not compatible with the service.
