iMEssages sync

[macphi99]

Hello

I notice someting weird on my iPad Air Wifi 8.3.

For only one thread with a friend, they are missing iMessages in the middle of the thread but all the iMessages appear on my iPhone and my Mac.

I send an iMessage from the iPad to this friend and her response came back on the iPad.
But I can't find no way to recover the 8 missing iMessages on the iPad...

Any idea ?

Very difficult question, even for Apple support...
