Lightroom Export Option Not Available

I think you're jumping the gun a little right now. Lightroom CC, as it is right now, is a good tool for users who want to download images quickly and get them shared on social media. It isn't a tool for doing all the things that are possible with Lightroom Classic CC. It may evolve into that kind of a tool eventually, but that isn't where it is right now. Use it for what is and watch it grow and develop. As it does, you can grow as well.

So it it possible to trial Lightroom Classic CC?   I had no idea I was downloading a light version of Lightroom when I opted for Lightroom CC.

"Save To" in LRCC is the equivalent of "Export" in LR Classic, although at this stage it has far less options than Classic.

However, the quality should be more or less the same, so what do you mean when you say "the quality is different"? Different to what?
