FNC Core instalation

I've installed Delphi 10.4.2 and then reinstalled, using the TMS subscription manager, the TMS components. Everything installed without errors. I'm able to compile and execute all the WEB Core demos.
But after installing FNC Core, I'm not able to compile the relative Demos. For instance, trying to compile the TMSFNCCore Demos\WEB\TMSFNCDataBinding, the compiler stops in WebLib.TMSFNCUtils in row 2971 telling that the stream does not have the size property ???
It refers to file C:\Program Files (x86)\Embarcadero\Studio\21.0\source\rtl\common\System.classes where I can see a size property defined for streams ...
I cannot figure how to fix this issue and I'm not able to recompile using 10.4.2 my projects which rely on TMS Web Core and TMS FNC components.

Any suggestions ?

Thanks

We are currently working on TMS WEB Core 1.7 that should fix this issue. We'll release a beta update as soon as possible.

Thanks you Peter,

Waiting patiently for this version
