Reminders not working after Ventura reinstall.

Hi, none of this worked. However, in my wander through the system and looking for other issues, I appear to have created two users - my 'original name' and another with the 'original name_1'. When I attempted to open Photos, there was nothing in the file. They are there in 'original name_1'. Is it possible that Reminders is looking for links or data in 'original name'? If so, any thoughts on how I unwind this issue/error/problem?

Thank you again for your reply.

Okay. Sure enough, the Reminders data is there. However, I seem to have several potential conflicts now. (Note: this is not a comprehensive list.) At first sight, the calendar data appears to be slightly different and some items are no longer showing. Also, I am concerned that whatever I do using the 'other account' will affect my Time Machine backups. I have therefore logged out and logged back in to the other account (I hope this makes sense).

My 'non-qualified' view is that I have inadvertently created a two users and my data has been split across these users, e.g. the Reminders info. In my simple terms, it looks like I need to merge these two 'users' such that I end up with only one, where all of our data resides. Sounds simple, but I assume this isn't. Any thoughts.

Thanks for your reply.

Yes, iCloud shows all of the correct data.

Thank you. I'll take a look.
