QE82Q70RAT Smart View S9+ No longer connecting

[Foz]

TV firmware T-MSMDEUC-1356.2

Phone S9+ One UI 2.0 UK 

We have 3 x Samsung phones in our house, all used to mirror to the TV, noticed last night this no longer works on any handset.

Rebooted TV, Router, switche etc.

TV hard wired (Ethernet)

Any advise ?

Very happy with picture on this TV firmware needs attention very buggy. 

When pressing prime button on remote it open yo Apple TV, if TV in standby it boosts up without surround sound connected.

Just to add something I feel is odd, I can cast YouTube to the TV from inside YouTube without any issues work 100%.

But it will not Mirror (smart view) the S9+ or S7 Android 8.0.0 march 2020 UK EE firmware.

Added: I am pretty sure it's the new TV firmware as all 3 phones cast to a £25 4k firestick on the same network in a differant room.
