[2021-05-01] Considering episode 5 of series 1:
In light of the very serious nature of the allegations against Noel Clarke raised by 20 women in the Guardian’s report, ITV has decided it is no longer appropriate to broadcast the final episode of the drama Viewpoint on ITV main channel this evening.

Despite being released on ITV Hub, the episode was not broadcasted on ITV, hence per TVmaze policy its airdate must be blank (unless, of course, ITV decides to air it on a later date).
The airdates for all episodes in the season must follow the winning source, or the airdate must be left empty if the episode never premiered on that source.
