I have found that the menus do not go deep enough. It would be helpful if they could go another two to three levels
Hi there! Thanks for your note.
Menus indeed only go 3 levels deep. It’s good to know that extra levels of depth might be needed. Curious about your use case (the types of products you carry / size of catalog) that requires more levels.
We’ll bring this back to the team. 
Cheers!
