This afternoon I left my app open in the browser with the console open for a few hours while I went for a bike ride.

When I came back, the following console messages had appeared…

Does anyone know what they could be about?

Violation message in DevTools

I keep getting this error repeating on one page [Violation] 'message' handler took 11225ms It’s not stopping the page displaying but the page does take an age to load and display. [image] Any ideas as to what it might be? And what I can do to speed the page up? Can I apply Lazy Load to none image repeats?
