Regression on potty

My daughter is 2.5 yrs old. We started potty traiing when quaratine was in effect bc of the corona virus. She did great was pooping aand peeing all day in her potty and the big potty. We felt it was almost time to start taking her places without a diaper. Then wham out of no where and 2 months of going great she is peeing all over the place. Every now and then she will pee i the potty but most of the time refuses. The weird and frustrating part is she loves to poop in it. We have resorted back to diapers bc i am at my wits end with pee cleaning. Yet if she has to poop the clothes come off and the diaper and no problems. Does anyone else have this issue? Any advice?
