How to set Global variables without OnStart

I'm trying to find information on how to use the new version of PowerApps without the OnStart parameters. I use OnStart quite frequently to set a whole host of global variables when the app launches, but can't seem to find where these should be saved now. In addition, I there is no option to select "Run on Start" while in developer mode to trigger the setting of these variables. Any suggestions on where to find information on this new "feature" or how to set Global Variables now on start of the app?

Thanks,

Renee

OnStart is deprecated in favor of StartScreen. See for details.

Moving forwards, the replacement of setting global variables in OnStart is to use Named Formulas instead (which is currently an experimental feature). To summarise the content of the help link below, instead of this...

Set( BoardSize, 70); Set( BoardLight, RGBA(240,217,181, 1) ); Set( BoardDark, RGBA(181,136,99, 1) ); Set( BoardSelect, RGBA(34,177,76,1) );

You would now do this in App.Formulas

BoardSize = 70; BoardLight = RGBA(240,217,181, 1); BoardDark = RGBA(181,136,99, 1); BoardSelect = RGBA(34,177,76,1);
