You’re welcome, it is indeed weird about latest update being not the latest update. But glad you’ve sorted it our.It only worked!
It seems version 102 I updated to via Hik Connect whilst at work earlier wasn't the answer for some reason even though that's the newest upgrade supported on Hik Connect
Version 108 appears to have sorted the problem! How weird
Thank you so much, it's only taken me about 3 hours of messing about over 2 days to solve! Glad I don't install these things for a living, I'd be tearing my hair out!
