Let's review your thread title: You stated, "the month on my iPad will not change when the first of the month appears". Where are you seeing "the month" on your iPad? Are you seeing it via the native Calendar app, a third-party calendar app or something else? Furthermore, being that we are not yet at the first of the month, is it possible that it is stuck on the today view, if applicable?
You went on to state, "Also, there is no July heading". Again, where are you trying to view the heading? Please be a bit more detailed so we can properly assist you. Thanks.

LOTS more detail is necessary.

Where are you seeing this? What app? The native Calendar? Something else? What exactly do you mean by "the month will not change"? Does this happen when you are scrolling in the app?

Please provide more details about what you are talking about.
