Ridley disappeared from britbox?

I was watching tv series Ridley on britbox, I paused for a few minutes, then app returned to home screen and tv series is not possible to find anymore. I was watching on TV with android tv and AppleTV app and I could see Ridley on TV home screen but when I tried to start watching from there it told me it is not available in my country :| Is it common that britbox removes access to productions out of nowhere?
