Hi,
thank you all for share your experiences.
Victor, in my case I get the issue when I work on Safari version 16.1 (18614.2.9.1.12) macOS 13.0.1 (22A400), but actually I have tried to use Chrome and works, I can save and change the events.
Thank You
I hope it can be useful for all of us
the plugin was deleted by me, but the problem remain the same
