Alm888: I believe this is the wrong thread for these discussions, because wild speculations and complaints about GOG's level and quality of support are neither FAQ, nor Troubleshooting.
Strictly original title wise yes, but I think this has become the general thread about all things Linux on GOG, simply because it's the biggest and the most established one and other threads are much less likely to gain any attention from GOG.
I'm not sure they are even reading this thread to be honest. Since @linuxvangog left the company, support was probably outsourced somewhere and no one is paying attention anymore.
And I would say not supporting more recent LTS can fall in the category of troubleshooting, since it will start leading to the increasing number of problems, no doubt as the time goes on.
vv221: Of course they don't know that the current Ubuntu LTS is the 20.04. I would guess that no more than one or two individuals at GOG know what "Ubuntu" is.
I really hope not, but I'm increasingly getting such impression as well.
