I am a longtime user of the iOs "Reminders" app. And I most commonly create new reminders through Siri, for example by saying "Remind me to pay the rent at 6pm."
These Siri requests started taking a slow, long time to actually create the reminder.
- I would make the Siri request, and then Siri would say things like "I'm on it," "Wait a moment," etc.
- A very long delay would pass. It would take up to 15 seconds before it would act.
- Then, it would actually even fail about 15 percent of the time, saying "Sorry, there was a problem with the app."
- A side issue that is truly a bug but not the point of this post is that, after the Reminders app was approved in iOS13, my default reminder list appeared totally blank when viewed in the web-based iCloud reminders app. (It was OK (after an initial delay of several days) in actual mobile devices and in the macOS app.)
What caused this slowness problem, and how to fix?
