Solved Windows 10 app NullReferenceException

When sending messages via the Windows 10 app most of the times I get a NullReference exception. It seems that the message gets sent (as I get responses), but it is not shown in the app UI. It is not shown in the phone messaging app as well.

Here is the log:

Arg_NullReferenceException

Hi, yes.

 

This issue was apparently fixed after updating the Windows app.

 

piggy backing on this -- I bought the Join app about 2 years ago via google play for a little over $5 -- was curious, do I have to buy the Windows 10 app on top of this?

just curious.
