I am making an app with 10 screens, which is the maximum that app inventor allows us, but when I try to compile it, I get a server error and come back later
Make a copy of your project, remove some pages and see if the app compiles.
Export your .aia file and upload it here.
What about providing the exact error message?
No. This is only a recommendation from AppInventor. Of course, apps with more than 10 screens can also be compiled, which later do not lead to crashes or memory issues as long as the screens are not too extensive and (in particular) are switched correctly.
