Until recently I got all freeview channels on my Veon TV with a UHF aerial(without using a decoder) Whats changed is a grey box popup message "Network change! Cell removed" with Yes & No options or OK on remote to exit & then TV3 & TV4, 8,9 & 11 disappears - when I tune TV the channels return & the same grey box msg "Network change! Cell removed" and within minutes the same channels disappear again no matter what options we select after this msg appears.
There is another small satellite dish outside/& cable inside our rental cabin - with a male jackpoint plug we haven't had to use, plus we got an old sky freeveiw box without a remote.
