PUN 1.75 is not compatible with .NET 2.0 Subset API Compatibility Level

Hi,

After updating PUN version from 1.73 to 1.75 iOS build gives the following error.

After changing API Compatibility Level to from .NET 2.0 Subset to .NET 2.0 I can take build successfully.

I think Photon3Unity3D.dll requires .NET 2.0 compatibility level anymore.

Is it possible to remove this requirement ?

Thanks.
