TL;DR
Why do I have to create a formula to use a boolean output variable as a visiblity condition in a flow? is there a better way to do this?
Detailed question:
I have a subflow (auto-launched) that has a boolean output variable. I'm trying to use this as a visiblity condition in a screen (component: Display Text). This is not working.
Subfow block:
Screen with condition:
I also created some test ones with a negated condition. After all, if TestOutput == true isn't true, then TestOutput != true must be, right?:
Result of running it:
For some reason the only ones that are actually displayed are those that depend on a formula variable I created:
The subflow:

Why can't I use these values directly? Am I doing something wrong?
Manually assign variablesin the subflow element work.
