Thanks for the additional details. Can you confirm that you’ve applied the optimizations in the help article linked in the previous post for Tasker and SharpTools related to Android battery optimizations (eg. Doze mode)? It also links to some Samsung specific optimizations you should make and a fallback option specifically for Samsung devices.
That’s weird on not seeing the Push Event Debug Notifications but still having the actions go through in Tasker. I’ll see if I can reproduce it… in the meantime, can you double check that notifications from SharpTools didn’t somehow get disabled at the system level… you can check using the system level App Info screen (Usually via Android Settings > Apps > SharpTools > Notifications but it varies by manufacturer)
Control from SharpTools vs from any other source shouldn’t matter… which makes me want to triple check that all the optimizations mentioned in the help articles have been applied. I guess you might even call these de-optimizations… Android has become much more aggressive with battery management and if you are seeing fast receipt of the events while SharpTools is foregrounded but delayed reponses while it’s in the background, that could be an indicator of system optimizations still being in place.
