  • macOS version: Big Sur 11.1
  • BetterTouchTool version: (please post the exact version - not just "the latest one")

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):

From my understanding, users of older Macs have looked for a 'Close' Gui element on Notifications in their apple scripts, which have since been changed in Big Sur. Perhaps this helps with the issue. The following workaround have some success, but they break when notifications are grouped by app -> https://apple.stackexchange.com/a/408602

I am having this issue still too. Are you still having this problem?
