I’ve previously created another calendar using the same account and a different account, and tested it by making the permissions public so that it can be shared.
As I mentioned earlier, I’ve confirmed that there are no restrictions on access to public calendars or external APIs.
But it still doesn’t work, which is why I’m asking this question.
Of course, I’ve tried clearing the cache, clearing the browser cache, and running in private mode, but none of those worked, which is why I’m asking here.
Please tell me what other methods I can try.
