Newbie (user name is weird, real name is Jaymer)
Mac, 2020.12.1, fresh install
Using cloudSampleSolution, 1.1.1 installed via Package manager
Discovered this on a MSSQL table I created a grid for, but was able to duplicate it on ordersTableView.
Edit the Form and change the RowHeight to 17
Then run the app and select ORDERS from the side nav menu
Scroll with the mouse scroll wheel and as it pages and refreshes the screen will become full of "Loading" records
(NOTE: attached image is MY Customers file, not the one supplied.)
Happens on other RowHeight settings adjusting back toward 25
Jaymer...
