Android with Unity does not build for 64bit in IL2CPP mode

[apvBri]

App can be built in 32bit mode (Mono scripting backend), but building for 64bit creates a Linker error:

"No action for the assembly TinCan, Version=1.3.0.0, Culture=neutral, PublicKeyToken=7e2d97554f738180 defined"

Is TinCan not compatible with 64bit publishing?
