A third season of hit comedy Derry Girls was confirmed in 2019 with six new episodes.
However filming was paused in 2020 due to the pandemic leading to a "substantially delay" to the release date.
Speaking at the Edinburgh TV Festival, Chanel 4's Deputy Director of Progammes Kelly Webb-Lamb said: "Our biggest frustration has been Derry Girls, which has been quite substantially delayed, because of pretty much everything we've made it's the hardest thing to make the social distancing work.
"It's the most close, sort of intimate production."
Webb-Lamb went on to say that scripted TV had been "probably the most disrupted" due to the ongoing pandemic.
"Unsurprisingly, and we've had a pretty thin year like most of the broadcasters with no significant new drama," she added.
When will Derry Girls season 3 air?
In February 2021, show star Nicola Coughlan revealed that filming was set to finally begin
She tweeted: "Can confirm Series 3 of Derry Girls is filming this year and I cannae bloody wait.
"Covid has pushed back filming several times which has been so s***e, but honestly the storylines in this series are the best we’ve ever done so I can’t tell you how worth it the wait will have been."
With that in mind it's likely Derry Girls' new series will be on TV in either late 2021 or early 2022.
Set in Northern Ireland in the 1990s, Derry Girls takes a warm and hilarious look at the everyday lives of ordinary people living in extraordinary times.
The series follows Erin (Saoirse-Monica Jackson), her cousin Orla (Louisa Harland) and friends Clare (Nicola Coughlan), Michelle (Jamie-Lee O'Donnell) and Michelle’s tag along English cousin, aka The Wee English Fella, James (Dylan Llewellyn).
