Hey,
Thanks for your reply!
I tried out using another (simpler and better build) navigation. - That wasn’t the problem.
But I found an element that was overflowing. - When I turned that off the, it worked perfectly.
Concerning the mobile interactions. I posted another thread on this forum specifically addressing the issues I was facing. As you seem to have pretty good expertise with these things you could maybe take a look at it too.
