I no longer have access to Unity 2021.1.28f from Unity Cloud Build. I don’t understand why removing the ability to choose an older version was even considered, this was the version that worked for me for one of my project for iOS, updating to latest 2021 broke ScalableBufferManager.ResizeBuffers (issue).
Why do that? Shouldn’t you thrive to at least give the option to build using any version and maybe don’t offer support for deprecated version? I mean this is an official service offered by the company that build the engine.
Most dev pick a version and stick to it, upgrading Unity version in my experience has never been a positive experience.
I guess I’ll just move to GameCI at least they offer nearly every single version and won’t remove them.
Please think about re-enabling the option to pick a specific deprecated unity version, and maybe add a big warning or something, this is really a bad move.
