This is not meant to disparage you or anyone else having difficulty, but can you quantify what exactly you find difficult in navigation? In otherwords “I want to go to X or I used to do Y, but don’t know how to now.” I ask so that I can help if possible.
It is different for sure, but I actually find I am moving through the site quicker than I did on the old one. In some ways it requires different ways of approaching it, but in many cases I’ve found a new approach let’s me find things quicker than before.
That is why I am interested in the problems people are having. I keep seeing people say it is too difficult, but without any explanation of why they find it difficult. For me it’s a little like someone saying that using the “new thing” to join two piece of wood together doesn’t work well, only to find out the “new thing” is a screw and they are trying to use a hammer like they did with a nail. It’s a difference between what you are trying to do versus how you try to do it, if that makes sense. In most cases the what is still there even if it requires a new how.
