Dear Community,

I just created a new environment, and assigned a security group to it. It's a large group with about 15000 users.
I imported my developed solution into that environment. I shared my canvas app with All Users. Still the application will not launch. The solution contains one canvas app, and multiple flows, and some connection references. So no dataverse tables (not sure if that is relevant for this problem).
This solution was formerly in the default environment, then I migrated it to a DEV environment, did some changes, and now hoping the get this in the PROD environment. What am i missing? I hope I do not have to set all those 15000 users security roles manually?

Thanks for your valuable insights here!
