This is indeed a peculiar case, @JulienH . Just to be sure, would you mind sharing with us, if the issue may happen if the shared list would viewed on Desktop?
Also, if you don’t mind, to have the list shared here as well? : ]
I’ve just tested a number of lists with greater than 10 POIs on both desktop and Android and all POIs are listed. Perhaps there is an issue with @Titoy 's particular list. Also, miight I suggest that this post should be moved to the How-tos section of Connect.
My friend tried to do special list (different than the list you see here above) and she told me that you can create (via email) and share those kind of lists but you can’t modify anything on iOS or even create them.
As i do not have access to a computer for a year or so (travelling) doing list as the link I shared was my only option.
Would be be great if google could make those things accessible on iOS. Maybe not feasible since I’ve read that many features available on desktop aren’t on mobile phone.
