I have disabled and re-enabled (toggled off and on) all permissions for MetaGrid Server and Keyboard Maestro in MacOS System Settings, under Accessibility, Privacy, etc. literally every permission I could find in there.
Is there something I’m missing? I emailed Support also.
Also tried doing this https://metagrid.zendesk.com/hc/en-us/articles/31480781739281-How-to-reset-accessibility-permissions-on-Mac and did a restart of my Mac. My buttons in MGP are still not triggering the custom Keyboard Maestro macros.
Opening the MGS Console window (mentioned below) did not turn out to be a reliable workaround - it only worked for 1 button press in MGP, and then failed.
Weirdly, if I open the MetaGrid server CONSOLE and keep it visible on screen, then it works. Why is this? What did you change with v.1.6.9 in this regard ?
