Samsung Tv source issue

Just a bit of feedback on Samsung Tv source control
Android phone o/s
2016/17 Samsung Tv
Using the new app
Automation for changing source has a glitch
If change source is selected as an edit in an existing or new automation a screen pop up box appears with “change source” written in it … and that’s it, nothing else, no source of any type is available
I should be seeing different sources to select
This is a recent issue as i have 2 automations created months ago that continue to work but are now un editable due to the issue with source selection

Wow, no reply in over 18 months and the problem persists.

What is the solution for being able to use select source again in smartthings scenes?(yes, my existing old scenes continue to work too).
