After calling the Change Variable block in Qlik Automate, the changes made are not shown in the sheet.
Resolution
In Qlik Cloud, automations make changes inside their own engine session. Those changes are not immediately visible to other sessions (such as in the Qlik Sense app UI) unless you explicitly save the app from that session.
Without a save, distribution to other sessions can take 20 to 40 minutes or not reflect at all in active UI sessions. The Save App block is intended ot be used in this instance.
Triggering the Save App block (available in the Qlik Cloud connector) signals the engine to do a DoSave, saving the app and reloading it in all open sessions.
Pass inputs from the app to the automation using the Execute automation button (in the app).
In the app, click Copy input block, then paste those blocks at the start of your automation.
Use Update variable (target the correct app and variable; set the definition or value as needed).
(Recommended) Immediately Get variable to verify the new value in the same run. Verify the output.
Add Save App (Qlik Cloud connector) once at the end of the flow so the UI reflects the change.
Since the Save App block is computationally heavy and limited to one execution per session. Place it once at the end of your automation.
