FMS 12 Development License would accept a few connections from FMGo. But FMS 14 Development License only accepts one connection from FMGo.
The documentation says:
Please note that the Development License only allows up to three simultaneous FileMaker Pro 14 and three simultaneous web-based clients for Custom Web Publishing, and one FileMaker WebDirect connection to access hosted FileMaker solutions.
My guess is that FMGo is seen as a Web Direct connection, is that right ? I wonder why FMI didn't allowed 3 or 4 connections among CWP, WebD and FMGo ?
In our case, that would be fine if can connect 2 FmGo to a database at the same time.
