Not sure if anyone else caught this yet but using Barracuda 3.0.0 verified package in Unity 2020.3.31f1 / 2021.1.16f1 and building an apk for android/build and play to android causes a huge list of shader errors. I can see this is probably a mismatch with the naming of the @2.0.0-pre.2 in the packagecache that the package writes to.
The builds work but I am noticing intermittent crashes in the builds which may be a side-effect of these errors…
