I have a customer who's current live version 8.4 2017-11-25 and runs a Background Task TimedMn every 120 seconds correctly.

I am testing the version 8.4 2017-05-14 (Build 707) to overcome a critical bug elsewhere and can see that, although the hal code is identical and everything the is set the same with current data, this background task is not running anymore.

Is anyone aware of any issues with Background Tasks with latest 8.4 versions?
