iPad feedback view missing - please help!

When I first started using Microsoft teams on my iPad, I was able to grade papers by having them load on a split screen with the paper on the left and the bee back area on the right. I don’t know what happened, but now the paper opens up in a large view and I have to go back and forth to enter feedback which has doubled my time while grading 100 essays. I have tried for hours but cannot get the view to go back to the way used to be – which is the way that it appears on a laptop. If anyone knows what I can do to get the split Feedback screen back, please let me know! Thanks
