calendar entries on phone and icloud but not on ipad

Thank you for your reply. I had verified all settings to be the same as advised. In addition I removed the accounts on both devices and reinstalled with identical settings. Yet I have the same problem as follows.

1. If I apply a calendar entry on my phone, it will show up on cloud (PC) but not on the Ipad. I did find if I go to the Ipad and turn calendar off and reopen, still no update. Yet if I go into settings and change a calendar setting (ex. turn week numbers from off to on) and it doesn't matter which setting I modify, Then the new entry will show up.
2. If I apply a calendar entry on my ipad it will update appropriatly on cloud and on my phone.
3. If I apply a calendar entry in cloud on my (PC) it will show up on my iphone but not the Ipad.
4. I had tried changing sync settings for all events but did not update.
5. I had tried selecting or changeing a schedule for Push, Fetch, or Manual but not update on the Ipad. At that point the Ipad calendar will update as stated in bullet 1.

I would think I should not have to go to settings and modify a setting on calendar before my Ipad calender will update.

If there was an icon on the calendar to manually initiate an update could be a solution. Yet I do not find any such option. Have to always modify settings to do so.

Tried several changes to setting in Ipad. Now nothing is updating?
