Can't upload .iq file because it is bigger than 5MB :-/

The iq file generated for my app is bigger than 5MB. It's 5.6MB actually. On the upload page, I get this message:

The following errors were detected in your app file
  • The uploaded file is bigger than 5 MB. Your file size is : 5621481 bytes.

It's really "code" - there aren't extra resources such as images and etc. It is indeed a very long program and all devices but the Edge 130 are supported (=many PRGs packed...).

Has someone met this problem?
What can we do about it?

I think the store will have to lift this limit, as we will have more and more devices to support (hopefully)...
