iOS 15 not support for my Calendar

Hello nirmail,

We'd like to make sure we're on the same page. To clarify, what calendar app are you using? Are you referring to the default iOS Calendar app, or a different one?

Also, what specifically is the issue you're facing. You've mentioned its slow, slow to do what? Does it launch slowly, or are you unable to tap into an event, etc?

Additionally, take a look over the tips below for if an app becomes non-responsive:

• If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open

Should the issue persist, let us know the additional details requested, and we'll continue from there.

Cheers!

nirmail,

So to clarify, after updating to iOS 15, you're no longer receiving your alerts or reminders on time for events in the Calendar app. Also, when trying to use the app, tapping into dates or events, it takes longer than expected for the app to respond?

If that's the case and the app itself is sluggish or non-responsive, take a look over the tips here:

• If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open

Let us know if the issue persist after following through those steps.

Cheers!
