Hi there!
Just update the smart speaker plugin to version 2.2.0 and it will work. You were using an old version 2.1.1.
I noticed it had an older version number a few days ago, but whenever I re-download it, it always gives me the ♦2.1.1♦ version...
I've tried it like 4 times over the last few days xP
I think it has something to do with the fact that it's only giving me access to the version that was available when I purchased it for 3$ like a year ago. I feel like maybe it's only giving me access to the old version that was 3$? lol
I haven't seen this happen with any other of your plugins, and I'm pretty sure this is a problem with itchio, though.
So maybe I should just buy it again at the new price? xD
