Hello,
I am trying to convert a B4J command-line application that uses FCMPush to a B4J UI application. However, when I move all the functions to the UI, I am encountering an error specifically in the GetToken function.
Has anyone experienced similar issues or have any advice on why the command-line version works, but the UI version fails at this point?
Any help or guidance would be appreciated.
Thank you!
