I figure I'll get locked out editing a large batch of stuff and likely forget later on to come back to it. So I figured I'd message you to see if you can fix it.
Love It or List It Vancouver appears to need updating. https://www.tvmaze.com/shows/14101/love-it-or-list-it-vancouver/episodes
Up til the end of season 3 it is good, starting S04E14 it needs fixing. It appears whoever was updating this swapped from the Canadian source (https://www.hgtv.ca/shows/love-it-or-list-it-vancouver/episodes/) to a US version (https://www.hgtv.com/shows/love-it-or-list-it-too/episodes). As the show is filmed in Canada, the Canadian source should be used.
Well, the producing country doesn't matter in this case. If HGTV show premiered first on HGTV in the US, we use US airdates. Refer to "Airdate owner" chapter of TVmaze policy https://www.tvmaze.com/faq/15/episodes
From Netflix you mean? You won't get them from the show's page, it requires meddling with Netflix's API. I can send you the instructions if you want, but it requires at least basic HTML knowledge and some manual work to extract image URLs.
