Following the recent update, when I turn my TV and Beam 2 on the app says I’m only receiving PCM 2, not Dolby plus etc.

if I unplug the power and restart the Beam,  full Dolby sound is displayed.

this issue was not present before the update to the app.

I use a Sony Bravia tv from 2018 using Arc not eArc, plus Apple TV 4K and Manhattan t3r Freeview box.
