Reminders app either changed or not working

Then you must not have a list named "To Do" in your Reminders app. I've been using a Mac for nearly 20 years in a tech career and using the Reminders app ever since Apple introduced it...it's always went to the Reminders list, not my To Do list. The only way this happens correctly for me now is if I completely remove my "To Do" list from the Reminders app...then Siri adds it to the only thing there (other than Groceries and Shopping), which is Reminders. This is definitely a change Apple has recently made. This also just just started happening with my wife's Reminders app.

If it's not too much trouble, please try adding a list named "To Do" and see if Siri adds it to that instead of "Reminders". I also tried renaming the To Do list to "Tasks" and that eliminates the problem. "Only" when there is a To Do list does it appear to happen. Thanks.

Chris...I posted in in "Using your iPhone" intentionally, but I just tried it on my 2018 iPad Pro and also on my new Mac mini...it's the same regardless of device.

The Apple Reminders app comes default with "Reminders" and "Scheduled" as you say...but you can add any number of other lists to it and they function exactly as the Reminders list. I have always had "To Do", "Groceries", and "Shopping" lists in the Reminders app in addition to the actual "Reminders" list. If I add an item to any of the other lists and associate a date & time with it I also see it in "Scheduled" as I should.

But that isn't the problem. As I stated in my original post...previously, and for several years since they added the Reminders app, if I asked Siri "Remind me at 6pm to take out the trash" that reminder would be saved in the "Reminders" list of the app. Now it's not...it's saved to the "To Do" list. This is what has recently changed.

If this is simply something Apple has changed, I get it. I've been an Apple fanboy long enough to know they often change things to suit them...and I'm fine with that. I just wondered if anyone else noticed the change.

Chris, I just now noticed the "Mac" tag displayed to the right of my level, but I didn't add it there, it's on all my posts in the discussion groups, regardless of where I post. It must be the forum software adding it. Regardless, I intended to post here in the "Using iPhone" section.

All this said, you resolved the problem! Thanks! I have always had the Reminders default list set to "Reminders" on all my iOS devices and my Mac. But somehow, on my iPhone and also my wife's iPhone the default was set to "To Do", thus causing the problem. I certainly didn't change that intentionally after all these years of it being set to "Reminders".

So...thanks for mentioning that which prompted me to check the default list on my iPhone!

Ahhh...that was my fault. I realize how many folks post here in the Discussion Groups and are pretty much novices. I was only trying to qualify that I’m a retired geek and should have said “...been using Apple products for 20 years”. Anyway, thanks for helping me figure it out!
