Power App Components not working with Global variables used with Input properties

[paulbeck1]

Problem:  Creating a new component with Input parameters.  When using the component and setting the custom input parameter with a variable, the value passes thru, as the variable is reset, the control does not update with the variable.  Replication Steps are recorded  in the 2 min 20 sec recording showing the issue.

Initial Hypothesis: I have a large Power App project that uses this technique a lot.  The global variable were working until Fri 14 Feb 2020.  I believe the Power Apps version has been updated and is causing the issue.  I have tried the work on multiple environments and tenants.  It is happening across them all.

I have a home screen in my application and when I login I have a variable that receives the value of the user's name and is used within the application.

When I published the application, the variable appears worthless.

And in the development environment it works normally.

Could it be a bug in the system?
