What was your previous iOS version, that is important, because iOS 12.4 only had the following changes. Please introspect how these changes can affect what you have posted.

Other improvements and fixes
This release also includes support for HomePod in Japan and Taiwan.
Nope that hasn't helped.
The online iCloud is correct, our iMac Calendar similarly so but since 12.4 update iOS devices not syncing. IOS have been updated every time there has been an update. Have deleted accounts, deleted apps etc but still not working properly
The easiest way to fix that problem would be, in my opinion, to delete all of the accounts and add them back.
