I started playing Solasta while using the PC client for Xbox. I could easily bring new mod.io modules into the game. Xbox stopped carrying it, so I switched to GOG. Now I can't import any mod.io modules into Solasta like I could with the Xbox client. Any thoughts on how to get around this? I don't really want to purchase the game (again) in a different client.

Why not? What's the problem exactly?

With Xbox I could import mod.io modules into my Solasta game. With GOG that doesn't work any longer. I saw a post on a different forum which said i should just drop them into my campaign folder but that didn't work either.

I usually don't mod my games and I also don't own "Solasta", so this comes from a position of someone without personal knowledge on the issue, but...
if neither Xbox nor GOG are supporting mods (at all, or any longer), what makes you think, that another client still would?

I finally figured out where my campaign directory was and everything is good. Thanks for trying to help.
