Yes, the problem is that I no longer know where the buttons are.

But years ago, when using old versions of MS Word, I also did not know where the buttons were and I also did not bother to read a manual or help.

Yet I could find easily any unknown menu or button. And nothing has changed with me. I still start using many programs that I have never used before, and in those I can easily find where the unknown buttons are. That is why I believe that the MS Word UI has become much less intuitive than in its old versions.

Moreover, I do not understand why they had to change the UI, because nothing that I have seen in the new versions appears to be an improvement, but just a wild shuffle of the locations of various settings and commands.
