So since updating to Good Lock 2020 I've noticed an issue on my Note 10+, I'm no longer able able to swipe down from anywhere on the homescreen to open the notification panel.
How do I know that Good Lock is the cause you may ask?
Here's how: The issue started a few hours after updating Good Lock, so I uninstalled Good Lock and then swiping down to open the notification panel worked again. I then reinstalled Good Lock and swiping down work for a few hours and then stopped working again. Uninstalled again, and it worked again.
Same with my Note 10+. I noticed this too the next day after updating good lock and nothing I do fixes it except uninstalling good lock.
I tried disabling and re-enabling the swipe down feature, reboot, cleared dalvik cache and no luck until I uninstalled good lock. More specifically after trying the uninstall and reinstall it turns out it's the "Task Changer" module when it's disabled the swipe down works again. Once enabled, eventually the swipe down stops working.
