Synching iPads

[ElleMrLA]

Hello Arlo,

I have a problem syncing two iPads. 
Mine is an iPad Pro 12.9, sixth generation. It is the Master.
I'm not sure about my colleague's iPad, but it's smaller. 

We connect the two iPads using "Adopt Actions..." My colleague has created a custom layout for his iPad (portrait). 

The text scrolling is done via automation tracks with jumps to markers in the text. 
However, on my colleague's iPad, the markers are not perfectly aligned at the top. The further the song progresses, the more the text shifts. 

We've also tried using my layout. Same result. The text shifts upward. 

What can I do about this?

BTW: All the best for the New Year!!!

Regards
Elle

How far off is it?

Are both devices using the current app version?
