Getting ITMS-4238 “Redundant Binary Upload” error

The workaround of changing the build number is working for me, with the following context:

• the app version status is "Prepare for submission"
• the new version number is well saved in iTunesConnect (pressing the save button on version page in iTunesConnect)

• the CFBundleVersion in the Info.plist is incremented (e.g. 1.2.1)

In this way, several build are associated to the iTunesConnect version.

Here is how it looks like in iTunesConnect (1.2 is the short version number, 1.2 and 1.2.1 are the bundle versions):
