Her absence was ignored during the programme, with presenter Charlotte Hawkins simply telling its 6am viewers: "We're here all the way through until 9am this morning, with Ben Shephard and Kate Garraway joining us at 6.30am."
Meanwhile, the show's weatherman involved with the clash against Morgan, Alex Beresford, had viewers questioning whether he was "missing" from the show. He had not been seen or heard on the programme since the argument where he accused Morgan of "trashing" Meghan.
Despite viewers wondering why he hadn't yet appeared, ITV told The Sun that he "wasn't scheduled to work Wednesday or today".
Hours after the speculation, Beresford posted his first statement, revealing he and Morgan "both wanted to be on the show Tuesday morning", the day after he stormed out.
"We both knew how strongly our opinions differed on the treatment of Harry and Meghan pre and post the interview that has split the world," he said.
After attempting to "reach a place of understanding, it's sad that we weren't able to get there", he said.
Yesterday, an emotional Reid opened the first show since Morgan left and addressed the "opinionated and disruptive" Morgan and the controversy.
The Sun reports she was "left in tears" when she learned her co-host had quit.
"A number of people will know the news and many of you will not and will be surprised that Piers Morgan is not here this morning. Now Piers and I have disagreed on many things, and that dynamic was one the things that viewers loved about the programme," she said yesterday,
"He is, without doubt, an outspoken, challenging, opinionated, disruptive broadcaster. He has many critics and he has many fans.
"You all know that I disagreed with him about Meghan's interview, he himself clarified his comments about her mental health on the show yesterday.
"There are many voices on GMB and everyone has their say. But now Piers has decided to leave the programme. Some of you may cheer and others will boo.
"It is certainly going to be very different. But shows go on, and so on we go."
It comes as Morgan tweeted his support of the cast and crew claiming: "They don't all agree with me, some don't even like me, but we were a team."
Meghan Markle had filed a complaint to the broadcaster's CEO raising concerns over Morgan's wording towards mental heath after she said she had suffered suicidal thoughts during her explosive interview.
ITV's royal editor Chris Shipp confirmed the rumours last night, saying Meghan filed the complaint on Monday to chief executive Carolyn McCall.
"I'm told that the letter was written by the duchess for one reason only — to raise and share concern over the serious impact that Morgan's comments could have on anyone struggling with their mental health or thinking about seeking help," Harper Bazaar's Omid Scobie continued.
Piers was "not going to back down" and Susanna was "seen in tears" after a series of meetings at ITV's studios failed to reach an agreement.
The source added: "It's been a difficult 24 hours for Susanna, too.
"She's exceptionally close to Piers, but is now left holding the baby. She also doesn't want to look like she condones his behaviour as she often disagrees with him, but respects his right to have an opinion."
Meanwhile, on the latest programme, co-host Kate Garraway said the show was now "different".
"That's the thing about Piers, he is very passionate, he does fly kites and have debates but it always come from a place of authenticity, he always believes in what he says.
"And he's left, he's decided to quit and has he put it himself, 'fallen on his sword of free speech', but as you rightly say, I've known him a long time before this programme, our friendship will go on, our personal friendship, and he's been very supportive of me personally.
"It's a different show but the show goes on."
