I'm late to the party here but:
Quote: Releasing a version with Python3 was a good idea
inputstream.adaptive has nothing to do with python2 vs. python 3 - it's a binary (c++) add-on.
Quote:I have Kodi 9.14 installed via LibreELEC
Assuming you mean 19.4 here.
LibreELEC runs their own repository for binary add-ons, if you can't see what you want there then speak to them about it.
Quote:the only add-on available for inputstream.adaptive is the "testing" version
If you're referring to 'inputstream.adaptive.testing' that is an unofficial fork made available through Matt Huisman/SlyGuy repository. Add-ons won't use that unless specifically instructed to. Btw it's deprecated now anyway.
Quote:Apparently, this is unfixable. Shows contempt for the worldwide users.
'Contempt' would be expecting that this forum is some sort of helpdesk for a paid service. No-one is paid to contribute to Kodi. Users and developers give up their free time to do this. Show some gratitude.
I understand these posts are written out of frustration and not being able to find an answer to your problem, but writing inflammatory remarks towards the community isn't going to get you what you want.

So am I. Perhaps think about adjusting your attitude and maybe you can also contribute to make things better.
