I believe this is an issue with Delphi and not with TMS FNC Cloud Pack.
Following instructions here to add the Android support .jar files: TMS Software | Android support for FMX applications
Delphi simply does not add the file. I've restarted Delphi. I've reported this to the Embarcadero quality system.
Is there another way to manually add a .jar file to a Delphi 11.3 project?
