Your opinion on ABCmouse

My little boy goes to a little school where the teachers come to the house and I was just informed that they would like me to put him on ABCmouse everyday for 15 minutes I have an iPad that they provide in case we need to do zoom. which I don't let him use only when we're on Zoom my question is have any of you parents used to ABCmouse and was it beneficial. He turn 2 in July.
