So today i got an email from apple saying that in order to submit my build to iTunes Connect i should give a description. Here is the needed part of the email. It looks like your app is using the calendar capability. Due to this being used, our app review team requires a description for why it is being used. Once description are provided for the capabilities used, and you attempt to upload again, the issue should be resolved. So which description should i provide exactly and where should i submit it?
