Groups Plugin not working anymore, how create light groups now

Hi Tim, and welcome to the Homey forum,

When you want (quick) help, try to provide as much info as possible, and use the correct app names, thanks. Some brands have 6 apps available for instance…

What app are you referring to, is it the < group > app: https://community.homey.app/t/app-pro-group-3-2-4-stable/3168 ?

If yes, what isn’t working properly you think? Did you read the manual (as linked above here) and tried all options first?
