I have created PowerApp directly from Power BI report. I have added absolutely all fields from one table (SQL db table) to the PowerApp.
The same fields are then displayed in a table visual in my report.
Whenever I select a row in PowerBI report, my PowerApps Gallery displays only that record - otherwise displays all.
I have only 6 records in my table so there can not be issue of having too much records.
BUT, there are some records that when I select them in PowerBI visual, it makes the PowerApps Gallery "dissapear"
Please see the attached images - first shows that row selection works correctly in Gallery and second shows, that gallery dissapears
