Sub Gallery Item Bug

[ajennings1]

I have a nested gallery that displays items from a SQL View. This view has records from multiple lookup tables joined together. PowerApps then uses a GroupBy on the Outer gallery items and each sub gallery displays all the records relating to each header.

The problem comes when I play the app and load the screen with the gallery in it. The first record from each sub gallery appears initially. See screenshot below:

Only until I scroll down a little further, then all the records appear like below:

Anyone know why this is the case?

Thanks

Hi @ajennings1 ,

This may caused by some preview or experimental features.

Could you try to turn off all experimental features and toggle off the following preview features.

@v-siky-msft,

Thanks for the suggestion. I think the problem was with the types of gallery. I saw a video with @mr-dang explaining GroupBy with nested galleries below:

My initial galleries were both flexible height galleries. I tried using the flexible height for the outer gallery and just a standard one for the inner gallery and this seemed to fix my problem. 

I think your suggestions would have also fixed this problem so I might turn them features off also.

Thanks.
