Hi!
As a pc user, I tend to forget that not everyone plays on a laptop/PC. Optimizing the UI for touch input and making the side panels hideable on mobile (since screen space is limited) was already on my todo list — I'll add this bug to the list as well. It won't make it into this weekend's update, but it's planned for the next one.
If I find a hotfix sooner, I'll post here again.
