Purchased the game a long while ago.  The Lovense integration got me to DL this and try it.  The issue is there is no Lovense showing in 2.9.  I can see the "Enable Buttplug.io".  Including a screenshot.

go to the discord server, must of the community is there.

We've just uploaded a new build and put instructions for connecting toys into a new Devlog post. Please check those out and see if it fixes the problem you are running into!
