Collections Don't Show All Items

I have a collection of 50 items. In the app I made, users go through all 50 items in the list and leave feedback on each.

Everything was working great, but something came up. After certain users see the first 20 entries, the collection appears empty for them until they resize the window. That is obviously ridiculous, but it at least functions. However, now users are getting to the point of seeing 40 items and the same thing happens. The collection (which has 50 items) appears empty for them, resizing the window doesn’t change anything.

The problem is that I need this data and I can’t “reupload” the Collection to try and fix it.

I opened a support ticket with Adalo, but they haven’t responded.
