Problems after installation (transition from LM)

I really like Zorin. I used LM for 10 years.
I have now installed Zorin.

My laptop is a Dell Vostro 5490.

I have some problems.

After click show more files, whitch i search. Nautilus not show files…

  1. Zorin connect is totally slow and freezes. I have a Samsung galaxy s10e. Everything is very slow on NTB.
