Page zoom keeps changing on ios devices

Hello,

I’ve had a problem for some time when using iPads and iPhones. Sometimes when viewing a page it is zoomed in so everything is bigger than it should be. At other times it is zoomed out where everything is smaller than it should be. Occasionally it is correct.

It’s very inconsistent. Sometimes it happens after I’ve made a change and have to refresh the page, sometimes it happens if I rotate the device from portrait to landscape.

Has anyone else experienced this? Does anyone know how to prevent it.

Thanks,
George
