I'm having issues when building a PowerApp, basically, I get the marching ants at the top of the screen pretty frequently, my CPU usage (on a Ryzen 5950X) goes through the roof and a load of 429 errors in the Java console which I guess is throttling of some kind, but I've only really come across this when using SharePoint and either migrating or hitting it too often with Flow. As my PowerApp is using SQL rather than SharePoint, does anyone know why am I getting it in PowerApps? I'm not doing anything particularly demanding when it happens, Just pulling back a record from SQL and reading it into a collection.

Thanks Chris, I’ll take a look to see what’s causing this. I couldn’t find any documentation on the monitor and how it works yesterday when I searched so that’s really useful.

Hi @robinisathakur,

An HTTP 429 errror means too many requests. You've likely exceeded your daily request limits. You can turn on the Power Apps monitor for your Canvas app to see if it is the app in particular that is sending too many requests.
