iOS 15.1 Calendar app is laggy and unreliable

When swiping between days, data often shows up as stale (events on the wrong day, or events at the "right" time but with wrong title).


Keeping the same day view open for up to 10 seconds seems to correct the issue (temporarily). This appears to be some kind of caching bug.


(This was *not* an issue in 15.0, 15.0.1 or 15.0.2. I have one MS Exchange calendar and three Google calendars.)

Its good that you try to stand up for apple. I just don’t feel like they’re trying I fix the issues here. While, as you mentioned, it isn’t the job of the people who monitor these forums, I feel like they could pass info on, or get just a couple guys who have a dedicated job of passing the complaints on.

They do have people (not all of them male) who are dedicated to the job of passing on complaints and feedback. They are the people who monitor the Feedback page. The people who monitor this form (also not all male) are far, far too busy to do what you want. The team is relatively small and this is one of the largest, busiest forums of its type in the world.


I'm not standing up for Apple. I'm just explaining how things work. You want them to work a different way and it's fine to want that. However, in the world as it actually is right now, complaining here will accomplish nothing other than perhaps some catharsis.

Based on the number of emails I’m getting I think it is very widespread indeed

If you mean emails from this thread, no, that wouldn't indicate it was widespread. You've probably gotten four of five notifications that I've posted in this thread, for example, and I don't have this problem. Other people have also posted multiple times. When an iOS problem is widespread, there are scores of very long threads.


It's actually kind of a disadvantage that it's not widespread. If it were, it would get Apple's full attention that much sooner. But, since it's not, you should keep submitting feedback.

Of this is apple rubbish response you need to take note. You have caused huge issues with peoples calendars due to poor testing and release mgmt.
the arrogance of apple is disgusting. Get this fixed before you loose many users.

How many times do I need to explain that Apple doesn't read here for suggestions or feedback? If you want Apple to know of your "disgust", use the appropriate mechanism:

It’s ridiculous. This has been going on since 15.1 was downloaded in my 12 pro max and I just upgraded me and my wife to a 13 pro max and we are both experiencing the same thing. Freeze on calendar cold start, lagging scrolling and launching of an event selection and it almost always starts on our earliest recorded calendar event….for me 2010. This has nothing to do with hardware or linked accounts and should be old news by now….
