BTT does NOT switch to old keyboard implementation even if it is checked

Update: strangely enough, not getting this issue for the last ~6 or so hours even after a system restart i.e. no secure input lock. Hoping this persists. Running v2.506.

Very strange. Secure input was behaving appropriately for the last ~18 hours - no issues with BTT, and new shortcut mechanism was working beautifully. I was hoping that this had resolved.

All of a sudden, secure input message in BTT returns - and the apps that are causing secure input to lock is whatever app is in the active window. I cannot figure out what is triggering secure input locking....

Note: restarting BTT will change the app that is activating secure input to whatever app that is the active window.
