    We also want to request a backport to 2021.3.x, this is affecting a lot of players.

    Bug still occurs in 2020 LTS. A back-port would be nice...

    You guys need to fix this in 2020 LTS as well. 2021 still has issues, including not building for PCs properly and we will not upgrade to it yet.
