Thanks. Those are useful changes. Meanwhile I have resubscribed and to multiple calendars and all is working.

Thanks again.

Thanks for this useful answer. I will do the multipl subscription thing. I already have my yahrtzeit subscription separate so I can do my study selections separately as well and most are still aspirational so I will do a calendars of just the ones I currently use and add the others later.

And of course many thanks for this amazing service. I wish you had a paid option so we could directly support your efforts.
