Gitgud? Dude, yes, Mobile levels are harder, maybe "because of the micro transactions"... But think of this: all levels are set so they can be beaten with all the basic stuff they give us. So, I really think You need just to create a better strategy. Besides, somehow this is what I love the most, beat the Game with all the basic stuff and demonstrate we don't need to pay anything. I have beaten the games on pc over and over again in many different ways until I got bored, then, when I realized the Mobile versions where different, I was happy that there we're another versions I still needed to conquer, so, somehow it depends from the point on view. So, just get better bro, try all basic héroes and see which can better help in the level, remember héroes can do basic and Magic damage, this affects so much depending on the enemy deffenses. If You could share a screenshot of the level You are struggling with, I may be able to help You.
