I don't understand, why GOG/CDProject does not fix it...
I imagine it is probably because CDProjekt has nothing to do with the development of Galaxy integration plugins, and only GOG, Steam, Epic, and I think Xbox integrations off the top of my head are official GOG integrations.
All of the other integrations including Uconnect are unofficial third party addons made by the community, and neither GOG nor CDProjekt are involved with developing nor maintaining them. So they're basically created by unpaid volunteers outside of the company if I understand correctly.
As such they wont likely get updated until someone outside of the company voluntarily feels like it, which is the nature of such things. It's like a 3rd party unofficial mod for a video game in that sense.
