Open Does join function with apps from appFactory

I am having problems getting join to send tasker commands into a taskerapp produced with app factory.
It does seems to function with other auto apps. Auto remote and location seems to be working.
But I have no success with join.
Is this supposed to be possible to do?

Then I will experiment some more.
(It is working fine with tasker, but not on my wife's phone with the app factory produced app)
I only need to receive push commands and send it into appfactory produced app. I don't not need to send, which properly works but I do not know.

I have set some settings in join from the app, just in case that triggered join to notice the app as a tasker "substitude", but no success.

Thanks
