All Devices Screentime showing different amounts on each device- it should match

[Irishappletech]

Hi is anyone else noticing that the screen time feature on iOS 13, iPad OS 13 and Mac OS Catalina is not showing the same amount on each device, even though its meant to. I have the "Share Across Devices" option turned on.

So on my iPhone now I see 1 h 13m and 56 m on Mac as can be seen in the screenshots, the same is true with iPad and my other Mac.

is anyone else noticing this and if so why

Thanks
