Cheating in IXL

Hi! I'm super sad about this. I love IXL and think it's great for reinforcing and practicing skills. I usually give it as homework with a chance to do work in class throughout the week. I've found many students now cheating. It's either clicking until they finally get the correct answer (this can be done in a minute) or using apps like GAUTH AI to take a picture and get the correct answer instantly. I opened my grade book tonight and decided not to waste my time grading it this week. How are you all dealing? I was thinking of continuing to assign it as is, and create short quizzes in IXL weekly to grade. I love that I can squeeze about 4 ixl's in for homework every week; I'm not sure I can do it all in class, and then there's always those out sick or that take with home to complete.
