I have a solution !
Thanks for your help, @alcampopiano, @p.colbert and @stucork - I didn’t previously know you couldn’t circular import, let alone know what that was.
So basically, I just got rid of the need for the circular import, and on the HomeScrn form (see cloned app), just changed the LinearPanel to a RepeatingPanel so there’s no need to import the components.
Fingers crossed, this won’t fail me too! PS you can find my actual published app, currently under development but half done at vsuite3.anvil.app (moving soon to vsuite.anvil.app). It’s an app aiming to be similar to, but much more simple than O365 and G Suite etc.
Thanks again for your help!
