Hey @fish098p, great questions! Welcome to the community and thanks for the queries!
This is usually against App Store rules and can result in blocked publishing. They need an account but you can use their credentials to publish to their App Store publisher account from your thubkable developer account.
Definitely! Once you publish, we would typically have 0 control over your apps functioning.
You only need to push an update when you’ve updated your project.
I think my verbiage up there may have been unclear. When I say Thunkable developer account, I literally only am referencing the time you spend on Thunkables website. It has nothing to do with your Apple/Android publishing account.
You’ll need an Apple developer account to publish to the iOS App Store
You’ll need an Android developer account to publish to the Play store.
