Morgan turned senior in 2019 and made her debut at the English Championships where she won gold in the all-around, finishing 1.75 points ahead of second place Kelly Simm. She was later selected to compete at the 2019 European Championships alongside Ellie Downie, Alice Kinsella, and Claudia Fragapane. Morgan competed at the British Championships and won bronze in the all-around, on uneven bars, and on balance beam. She placed fourth on floor exercise. At the European Championships Morgan finished fifth in the all-around qualification but did not advance to the final due to teammates Kinsella and Downie scoring higher. Morgan was also a reserve for the bars and beam final. Just after the European Championships Morgan sustained an injury. She healed in time for the 2019 World Championships in Stuttgart as travelling reserve but she re-injured herself and Kelly Simm took her place. In November Morgan made her international comeback at the Cottbus World Cup in Germany. She qualified to the uneven bars final where she scored 13.766 and placed seventh.
