I have a very large Sharepoint list that contains different projects. In my PowerApp, I group by these Projects by using a flexible height gallery that contains a button to expand the project and then a nested gallery to display the items corresponding to the project (This one is not a flexible height gallery because then I would have two scroll bars).
The problem is that the flexible height gallery seems to have a hidden maximum template height because when I expand a small project (20-30 entries) there is absolutely no problem and everything is working fine.
However, when I expand a big project (100 - 200 entries) I can scroll through like 50 - 60 of the entries before they just get cut off.
The height of the nested gallery is calculated by multiplying the number of entries in the project by the template height and works just fine (I checked the height property and it was correct) so there must be a problem with the flexible height gallery template height which seems to be limited.
Microsoft doesn't have proper documentation of PowerApps anyways and in the gallery documentation this is not listed as a known limitation.
Does anyone have any experience with this problem and knows how to solve this Issue?
Thank you
