Crossfade clips

Hi, i have just installed the latest Audacity version 2.3.3, but now in all of my projects, and even in new projects it seems to be impossible to crossfade clips. I get this message (attached) (translated: invalid selection, more than two audioclips selected)
Please help me! Thanks :slight_smile:

Can somebody PLEASE help me out?

I’ve never tried a “crossfade effect”, but I’ve made [u]manual crossfades[/u].

Please don’t double post. I have replied here:
I’ll close this topic to avoid confusion.
