I was trying to download a movie and then somehow this error occurred, kindly help.

Open Calendar App from the Home screen.

Next, tap the Calendars button at the bottom.

You should now notice a section called On My iPhone with several suspicious calendars listed below it. ...

Tap on the i button next to the suspicious calendar.

Now, tap on Delete Calendar.

thats a spam

go to seetings /calendar/ acc / there is an event of calendar click on it and delete it

Kirk, this is not the best method to do this Settings > Calendar > Accounts > Subscribed Calendars then remove rogue ones is the best method for iOS 14.x

Best not to abbreviate when giving instructions, people will take “acc” literally.

Deggie just trying to pass my time here sharing some info i know but i thought they will understand it but it seems that no😂 ( i will excuse myself because english is not my first language😅)

That is good you are doing that and your English is quite good but when doing steps, links, etc. you do need to use the exact verbiage since 49% of the public is below average.

Thank u deggie ( yeh u right have to be more specific and use the exact word )

ps: good job with the help u give here , complimenti😉
